* CORDA-3917 Update to Jackson 2.9.8 (#6493)
* Update to Jackson 2.9.8 to address multiple security issues, and update warning note about
updates to clarify that it refers to 2.10+. When the note was added 2.9.7 as the highest
available version in the 2.9.x series.
* Add PR code checks Jenkinsfile
* CORDA-3916 Update to BouncyCastle 1.61 (#6492)
Update to BouncyCastle 1.61. Updating one version at a time to mitigate risk of a complex breaking change being introduced.
* Added missing collection of JUnit tests and logs

Add details of the signature provider and key algorithm if `InvalidKeyException` is thrown when constructing a `ContentSigner`, in order to be able to usefully diagnose incorrect signature providers or similar errors.
* NexusIQ every build related to Corda X.Y (GA, RC, HC, patch or
snapshot) uses the same NexusIQ application
* NexusIQ application application has to exist before a build starts
* Fixed repository name for publishing, use OS instead of Ent one
* every build related to Corda X.Y (GA, RC, HC, patch or snapshot) uses
the same NexusIQ application
* NexusIQ application application *has* to exist before a build starts
* Use a virtual repo (corda-remotes) containing all Corda repositories with dependencies
* activated when CORDA_USE_CACHE environment variable is set
* Update Jenkins configuration to use new functionality
* it does *not* affect local builds as long as environment variable is not set!
These tests were removed after doing a merge from 4.4. They needed
updating after the changes from 4.4 anyway. These have been included in
this change.
Also fix kill flow tests and send initial tests.
Maven central will not allow the node-driver to be published without a Javadoc `.jar` file, even if it is empty. This adds an empty Javadoc `.jar` to the output.
When a non-database exception is thrown out of a `withEntityManager`
block, always check if the session needs to be rolled back.
This means if a database error is caught and a new non-database error is
thrown out of the `withEntityManager` block, the transaction is still
rolled back. The flow can then continue progressing as normal.
* CORDA-3722 withEntityManager can rollback its session
Improve the handling of database transactions when using
`withEntityManager` inside a flow.
Extra changes have been included to improve the safety and
correctness of Corda around handling database transactions.
This focuses on allowing flows to catch errors that occur inside an
entity manager and handle them accordingly.
Errors can be caught in two places:
- Inside `withEntityManager`
- Outside `withEntityManager`
Further changes have been included to ensure that transactions are
rolled back correctly.
Errors caught inside `withEntityManager` require the flow to manually
`flush` the current session (the entity manager's individual session).
By manually flushing the session, a `try-catch` block can be placed
around the `flush` call, allowing possible exceptions to be caught.
Once an error is thrown from a call to `flush`, it is no longer possible
to use the same entity manager to trigger any database operations. The
only possible option is to rollback the changes from that session.
The flow can continue executing updates within the same session but they
will never be committed. What happens in this situation should be handled
by the flow. Explicitly restricting the scenario requires a lot of effort
and code. Instead, we should rely on the developer to control complex
workflows.
To continue updating the database after an error like this occurs, a new
`withEntityManager` block should be used (after catching the previous
error).
Exceptions can be caught around `withEntityManager` blocks. This allows
errors to be handled in the same way as stated above, except the need to
manually `flush` the session is removed. `withEntityManager` will
automatically `flush` a session if it has not been marked for rollback
due to an earlier error.
A `try-catch` can then be placed around the whole of the
`withEntityManager` block, allowing the error to be caught while not
committing any changes to the underlying database transaction.
To make `withEntityManager` blocks work like mini database transactions,
save points have been utilised. A new savepoint is created when opening
a `withEntityManager` block (along with a new session). It is then used
as a reference point to rollback to if the session errors and needs to
roll back. The savepoint is then released (independently from
completing successfully or failing).
Using save points means, that either all the statements inside the
entity manager are executed, or none of them are.
- A new session is created every time an entity manager is requested,
but this does not replace the flow's main underlying database session.
- `CordaPersistence.transaction` can now determine whether it needs
to execute its extra error handling code. This is needed to allow errors
escape `withEntityManager` blocks while allowing some of our exception
handling around subscribers (in `NodeVaultService`) to continue to work.
