After trying to find out what was the problem, we figured out that some session
that are returned to the XAPool are not properly cleaned up and returns to the
pool with registered Xid.
As soon as they are reused the above exception is thrown.
Why is the transactionContext not cleaned or at least validate when session is
borrow from the pool ? to ensure that the state is valid for the future use.
There is a cleanup method in TransactionContext.java class that reset the
registered transaction
line 806-809
public void cleanup() {
associatedXid = null;
transactionId = null;
}
but this method seems to be never called.
