First cut of telemetry integration.
Open telemetry can be enabled in two ways, first is via an opentelemetry java agent specified on the command line. With this way you get the advantage of spans created from other libraries, like hibernate. The java agent does byte code rewriting to insert spans.
The second way is with the open telemetry driver (that links with the opentelemetry sdk). This is a fat jar provided with this project and needs to go into the node drivers directory.
There was a mistake made when we first introduced notary request signature checking, in that we didn't wrap it in SerializedBytes so it always got deserialized as part of the flow message payload. So to check the signature, it has to be re-serialized. This means for cross-version compatibility we can never change the serialized format of NotarisationRequest. In this case we need make sure that every SecureHash mentioned in that data structure is a distinct instance, even if the values are repeated / identical, as that is how it was in Corda 1.
With the introduction of interning of SecureHash, this ceased to be true once again, including undoing the attempts to force it on the sending side that had been introduced in previous versions of Corda. So here we introduce a way to force it, and consolidate the forcing to distinct SecureHash instances in the NotarisationRequest itself, rather than leaving to the caller of the constructor to remember to do it, so that serialized form will always be as per Corda 1.
ENT-6947: Implement interning for SecureHash, CordaX500Name, PublicKey, AsbtractParty and SignatureAttachmentConstraint, including automatic detection of internable types off companion objects in AMQP & Kyro deserialization. In some cases, add new factory methods to companion objects, and make main code base use them.
Performance tested in performance cluster with no negative impact visible (so default concurrency setting seems okay).
Testing suggests 5-6x memory saving for tokens in TokensSDK in memory selector. Should see approx. 1 million tokens per GB or better (1.5 million for the tokens we tested with).
The warning is misleading because it is emitted in the case where the
ServiceHub reference is not null but one or more state pointers were
configured to not be automatically resolved by the transaction
builder.
* ENT-6588 Restrict database operations platform flag
Put the restricting of database operations in `RestrictedConnection` and
`RestrictedEntityManager` behind a platform version flag.
`RESTRICTED_DATABASE_OPERATIONS = 7` was added to signify this.
If the version is less than 7, then the database operations will not be
restricted. A warning is logged to indicate that they are using
potentially dangerous methods.
If the version is 7 or greater, then the database operations are
restricted and throw an error if called.
A public version of `FlowManagerRPCOps` which does not live in an
internal package has been added. This new interface shares the same name
as the internal one.
Because of the name sharing, the internal version has been
`@Deprecated`.
`FlowManagerRPCOpsImpl` implements both the new and old interfaces. This
allows for backwards compatibility, allowing old shells or clients to
call the old interface on newer nodes without breaking.
* ENT-6357: Deserialize LedgerTransaction elements for each Contract.verify().

* Refactor BasicVerifier to be package private instead of public.
* Simplify verifyConstraints() operation.

* Ensure tests also run notary nodes "out of process".
* Streamline SerializationContext switching.
* Cache deserialised cryptographic instances during contract verification.
* Invoke Class.forName() instead of ClassLoader.loadClass() to reduce contention on the system classloader's lock.
* Deserialization cache key now pre-computes its hash code.
* Allow AttachmentsClassLoader to be used concurrently.
* Cache all Envelope objects for reuse during contract verification.
* Generate CertPathProxy hash code using conventional algorithm.
* Adjust CustomSerializer.Proxy to allow better access to SerializationContext.
* ENT-6330 Fixed reading jar entries in memory
This is a trivial fix that is however enough to allow to send zip bombs as attachments without the node crashing, a size limit could be added for increased reliability
* added attachment cumulative size check
* added compression ratio check
* added unit test and moved the code to a standalone verifier object
* removed attachment check from AttachmentClassLoader to minimize performance impact
* CORDA-4098 assumption test (#6871) (#6873)
