In Corda 4, FinalityFlow was updated to become an initiated flow, in order to ensure a node does not have to accept any signed transaction it receives without being able to check it first. The old behaviour of FinalityFlow was gated behind a targetPlatformVersion check, to prevent apps targeting V4 from using the old behaviour.
This is problematic for a few reasons. For an app wishing to be backwards compatible with a version running on V3, this forces the app to set targetPlatformVersion = 3, even if the app is thoroughly tested against V4. This goes against the purpose of the targetPlatformVersion. Another consequence is that an app remains pinned to targetPlatformVersion = 3 until it is sure that there are no other apps running at a lower version in the network, which would prevent newer versions of the app from taking advantage of features gated behind targetPlatformVersion checks. (Note that the restriction only prevents a new version of the app from initiating FinalityFlow with the old version - the old version is able to initiate a FinalityFlow and the new version will handle it, assuming the app has been written correctly.)
This fix removes the targetPlatformVersion check from FinalityFlow, and also provides a few documentation updates to clarify what level of testing would be expected to set a targetPlatformVersion.

CORDA-2595 fix test and address code review comments
CORDA-2595 address code review comments
* First pass at fixing 2563.
* In memory KMS now maps keys to IDs.
* CreateDatabaseAndMockServices now creates a persistent key management service and a can take a persistent identity service, so now the external id mapping works for mock services.
* * Created a helper for mock services which allows the creation of a mock services with persistent identity management service key management service and vault.
* MockNode now uses persistent key management service - not sure why it didn't do before?
* * MockNode now uses BasicHSMKeyManagementService
* Updated api-current file
* Little fix required after rebase to master.
* Fixed broken test.
* Added informative error messages to UnsupportedOperationExceptions thrown by E2ETestKeyManagementService.

Added an isLegalIdentity function that allows the client to check if the Node represents the requested CordaX500Name without throwing an exception if it does not.
With (Contract JARs) rolling upgrades the downgrade rule cannot be effectively check as the platform can't tell the difference between a transaction that's downgrading because of an attack, vs a transaction that's downgrading because Alice has upgraded but Bob hasn't yet. During a rolling upgrade we would expect state versions to fluctuate up and down as data gets read/written by a mix of nodes. With the feature as implemented Alice will upgrade and start trading with Bob. Bob will be able to read and process the states Alice sent him, but the moment he tries to consume such a state he will fail. This will result in cascading flow deaths and a hung business network the moment an upgrade starts.
Previous implementation was in LedgerTransaction and focused only on contract classes,
but every package matters.
Also fixes some exception types and does misc refactorings.
Take out a useless parameter from a method that was added to the public
API, document it. Add some comments explaining more about why we are
looking up attachment versions in WireTransaction.toLedgerTransaction.
* Add FetchParametersFlow
* No downgrade parameters in ResolveTransactionsFlow
Make sure that parameters in the transaction
graph are ordered (this is to prevent the downgrade attack, when the
malicious notary and participants sign transaction that shouldn't be
notarised otherwise). We ensure that by checking that epochs of network
parameters in the transaction chain are ordered.
* Addressed some minor items from RP review feedback.
* Refactoring following rebase from master.
* Address RP PR review comments (round 2)
* Addressed a couple of minor PR review points.
* Renaming of unit tests and cleanup.
* Changes discusses with RP to ensure Network Param checking is applied at txn verify time + resolve order checking gated on existence of tagged NPs in txn and associated minimum platform version.
* Do not fail on missing ServiceHub impl + return nothing if txn not NP tagged.
* Unify HistoricNetworkParametersStorage and
NetworkParametersStorageInternal
* SignedDataWithCert implements NamedByHash
* Cleanup
* Move parameters ordering check to signed transaction resolution
* Fixes after merge, address comments
* Address Andrius comments
This includes all of the cash selection logic, JSON support using jackson and a bunch of utilities which are not relevant to contract verification. The exception to this are Interpolator which has been moved to the IRS demo, and PhysicalLocationStructures.kt which is now in explorer.
* Start pooling classpath scanning
Quickly patch synchronisation of attachment class loader cache. Needs a revisit but more complicated due to DJVM.
Annotate away for DJVM
Take ClassGraph utils into their own file so we can exclude for DJVM
Clean up a little
* Daemonize the threads
* Seems to be some concurrency problems with use of ClassGraph. Using a mutex for now to work around.
* Removed `restart node successfully with suspended flow` as it duplicates `TraderDemoTest#Test restart node during flow works properly`
* Removed the need for a notary
CORDA-2497 fix
* Added test to show the fix working.
* Now backwards compatible.
* Refactored out some duped code.
* Added better explanations for what's going on.
* Fixed test which was failing due to the serializationEnvRule problem.
* Addressed Tudor's review comments.
There were two issues:
* The original "sealing violation: can't seal package net.corda.nodeapi" issue was due to the isolated CorDapp containing some code in the net.corda.nodeapi namespace. This has been moved to the isolated namespace.
* The test was not correctly creating the second transaction with the dummy command
The gradle process that runs the tests keeps an exclusive hold on built jars in Windows, which means if a test wants to get hold of the CorDapp, and it's requested from the same module, it will fail. Now instead of deleting the "libs" dir we just use the latest created jar.

The API has been reverted to be completely ABI compatible with V3, and the small changes that were made to the wire format in https://github.com/corda/corda/pull/4260 have also been reverted.
* Undo renaming of c'tor parameter (API break).
* Re-introduce default param in CordappImpl c'tor.
* Make 'msg' a property of PermissionException to make it serializable.
* Deprecate `CommandWithParties.signingParties` as it should not be used in contract verification code as it is non-deterministic.
* Remove the remaining usage in contract verification code - replaced by signers collection.
Corda Node ensures a given contract class and version can be sourced from only one signed and trusted Attachment (JAR).
An attempt to import a signed JAR as a trusted uploader (or promote to be trusted) with a class and version already present in the other trusted Attachment will raise DuplicateContractClassException.
Minor fixes to Hibernate Attachment Query parser (original query to select attachment without signers would always return no attachments)
Move Raft and BFT-Smart notaries back into node to preserve backwards compatibility.
* Allow overriding full node config when using internal mock network parameters.
* Make BFT-Smart notary start up in prod mode as well

* ENT-2923 - remove db access code from the verification thread pool
* Remove worker pool for tx verification and disable db access.
* Address code review comments
Apps may depend on the previous behaviour of catching Throwable rather than just Exception. Better to not risk this break and instead provide a helper to throw Errors.
Also using Consumer to avoid ugly usage in Java for doOnSuccess and doOnFailure.
* Update the documentation for trackBy to better indicate that updates are not filtered according to the query criteria
* Add a test that shows the behaviour, which is skipped for now until a solution is implemented.
* Remove discrepancies between OS and ENT caused by manifest metadata.
Unsigned (until identify why signing causes different .EC file)
* Align comments between OS and ENT.
* Internal classe were being exposed and have been hidden
* The single flowLogic instance has been changed into a lambda producer. Flows may not be written to be executed twice, especially if they hold internal state.
* Added JVM c'tor overloads
* Fixed incorrect attachment loading integration test
`AttachmentLoadingTests.test that attachments retrieved over the network are not used for code` was a false-positive - it was incorrect on multiple levels. Fixing it required updating the finance:isolated CorDapp, at which point it was given the new MANIFEST metadata for V4, and moved out of the net.corda.finance namespace to avoid package sealing issues.
The new test exposed a bug in the LedgerTransaction verification logic. This was cleaned up as it was too easy to verify on the wrong instance.
The overload that takes in a String does NOT check that the exception thrown has that message, which is what these tests are assuming. Rather it's the assertion message when the test fails.
* CORDA-1839 - Remove race condition between trackBy and notifyAll
* Fix null check
* Improve filtering
* Switch equality test to refs
* Refine filtering of seen updates
* Add entry in the changelog

* api-current.txt change to remove warnings of abstract methods in new interfaces.
* Fix indent
TestCordapp has now two implementations to clearly separate the two use cases it has in the Corda repo:
* TestCordappImpl which implements the revised public API of TestCordapp; namely that a TestCordapp instance references a real CorDapp jar on the classpath. This is either an external dependency jar in which case it’s taken as is and given to the node, or it’s a local gradle project in which case it’s compiled using the gradle “jar” task to generate the CorDapp jar. This approach means the jar has all the original CorDapp versioning information, which is important that it’s correct when testing. To this end, TestCordapp only needs to expose the ability to specify the app’s config. All the remaining properties have moved to CustomCordapp.
* CustomCordapp for creating arbitrary custom CorDapps, including specifying the jar’s MANIFEST values. This is internal API and only used for testing the platform. Technically this shouldn’t implement TestCordapp but does so to reduce the complexity of the driver and mock network.
* Make TimedFlows retry forever, and cap the growth of the time out interval.
* Only time flows for restart if that is sensible (i.e. notary flows that actually have an alternative node to talk to).
* Move check for multi node notary into getter so it the `canBeRestarted` attribute can't be set too late.
* Make restartable timed flow a concept on SubFlow metadata and the relevant events so we can handle it properly for subflows based on their metadata.
* Addressing review comments.
* Consistent naming
* Update documentation
* Addressing documentation comments.
* Refactor into attachment service

1) TwoPartyTradeFlowTests - restructured - saving transaction just after creating a state, as it's needed for the next TransactionState to be verified (for non-downgrade rule), enable more tests which were set as @Ignored, left 3 TODOs as 2 tests were slightly modified, need further investigation
2) MockService method loadContractAttachment always returns a dummy Attachment which means it has a default Contract Class Version number 1 used for signature constraints non-downgrade rule.
3) TransactionSerializationTests - added a fake transaction which created fake stated used as input state and using real (not mocked one) implementation of loadContractAttachment
Contract class version non-downgrade rule is check by LedgerTransaction.verify().
TransactionBuilder.toWireTransaction(services: ServicesForResolution) selects attachments for the transaction which obey non downgrade rule.
New ServiceHub method loadAttachmentConstraint(stateRef: StateRef, forContractClassName: ContractClassName? = null) retrieves the attachment contract related to transaction output states of given contract class name.
TransactionBuilder loads attachment using attachment storage instead of CordappLoader,
contract class version is now Integer (format and stored in db as Integer).

* CORDA-2115: Notary whitelist verification changes
- For regular and contract upgrade transactions: check that the notary is in the network parameter whitelist
- For notary change transactions: check the the new notary is in the network parameter whitelist. This enabled support for network merging: the old notary doesn't have to be in the current network's notary whitelist for re-pointing old states to another notary.
These checks are done during transaction construction/verification and also by the non-validating notary.
