I'm still waiting for someone to tell me I'm wrong about this. Should I
create a JIRA issue for it?

Hi Ryan,

You could open an issue, but to fix this we really need a new/extended
JDBC store implementation.  The current implementation was not really
designed to support recovering XA transactions.  It was always
intended that the Journal would be in charge of doing that bit of
work.  The new implementation would need to record the in progress
tx's in the JDBC database before they are committed so that way on
broker restart we can reload the in progress transactions.

If you want to take a crack at implementing this please feel free.
I'd be happy to provide assistance/tips.

Regards,
Hiram
