recovery leaks xaresources
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 5.0.0.M1, 4.15.3, 4.6.1.CP12
Reporter: Jonathan Halliday
Assignee: Jonathan Halliday
Fix For: 4.6.1.CP13, 4.15.4, 5.0.0.M2
XARecoveryModule._xidScans may grow without limit in cases where an xa recovery plugin is
both a) returning new XAResources rather than validiating and reusing the previous one and
b) the isSameRM implementation provided by the driver is unable to recognize the
equivalence of two such XAResources.
To prevent such leakage we should remove any scan entries that have not been updated
recently, thus ensuring expiration of entries that are not refreshed by the
refreshXidScansForEquivalentXAResourceImpl correlation mechanism.
