Andrew Dinn commented on JBTM-217:
----------------------------------
The current(WeakHashMap) implementation works round a problem with synchronization
execution order dependencies. It is required until synchronization ordering can be
implemented in both the local JTA and JTS.
Contention on SychronizedMap in TransactionLocalDelegateImpl.java
-----------------------------------------------------------------
Key: JBTM-217
URL: http://jira.jboss.com/jira/browse/JBTM-217
Project: JBoss Transaction Manager
Issue Type: Bug
Security Level: Public(Everyone can see)
Components: JTA Implementation
Affects Versions: 4.2.3
Reporter: Phillip Thurmond
Assigned To: Andrew Dinn
Fix For: 4.4
Under heavy loads, I'm seeing contention on the object map in
TransactionLocalDelegateImpl.java. Can this variable be changed to use ConcurrentHashMap?
