-----------------------------------
Summary: JCA recovery race condition
Key: JBTM-1354
URL: https://issues.jboss.org/browse/JBTM-1354
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public (Everyone can see)
Reporter: Tom Jenkinson
Assignee: Tom Jenkinson
Fix For: 4.17.3, 5.0.0.M2
Evidenced in SimpleIsolatedServers::testSimultaneousRecovery
Basically XATerminatorImple -> SAA::activate() -> XAResourceRecord::restore_state() -> getNewXAResource() -> XARecoveryModule::getNewXAResource()
At this point _xidScans may be none-null but still only partial from the first scan: periodicWorkSecondPass -> bottomUpRecovery -> resourceInitiatedRecoveryForRecoveryHelpers -> xaRecovery
if (_xidScans == null)
_xidScans = new Hashtable<XAResource,RecoveryXids>();
What I am not sure of is whether we should synchronize bottomUpRecovery and getNewXAResource as that would stop this race condition. Gonna give that a whirl.
