Hey, while working with the new 1.13 JDBC XA sink I had state restoration errors connected to XaSinkStateSerializer with it's implementation of SNAPSHOT using anonymous inner class, which is not restorable due to not being public. When changed to implementation similar to CheckpointAndXidSimpleTypeSerializerSnapshot state restores without problem.
Should I provide Jira ticket and patch for this error? Sorry if that's obvious. Thanks, Maciej
