[jbossts-issues] [JBoss JIRA] Commented: (JBTM-328) Synchronization bug in org.jboss.txbridge.TxBridgeManager

Pavel Kadlec commented on JBTM-328:
-----------------------------------
I try to remeber on that issue. I think that I meant it in the way that those two lines
are not synchronized together in the following way
synchronized (lock) {
Xid xid = txIdMappings.get(externalTxId);
if(xid == null) {
cxid = createMappings(externalTxId);
}
}
Two threads can together receive null for the same externalTxId and both threads can
create mappings. I thought this is not correct behaviour.
