  | What I thought that should be happening, is TransactionImpl aways storing the prepare on disk. That way an empty transaction would be recovered instead of "killing" the whole branch on the TM.

My understanding, is that if the transaction branch is empty, then prepare should return return XAResource.XA_RDONLY

(See ServerSessionImpl.XAPrepare)

And then the transaction manager knows not to ever call commit or rollback for that branch.

I however recommend clarify these finer points of XA with a member of the transactions team.
