Mark Little closed JBTM-610.
----------------------------
Resolution: Done
Good catch Andrew. Implemented proposed change for now and working on reducing the
synchronization overhead.
Restore mutex handling on LockManager
-------------------------------------
Key: JBTM-610
URL: https://jira.jboss.org/jira/browse/JBTM-610
Project: JBoss Transaction Manager
Issue Type: Task
Security Level: Public(Everyone can see)
Components: Transaction Core
Reporter: Mark Little
Assignee: Mark Little
Fix For: 4.8.0
It looks like someone tried to optimize the synchronizations around LockManager, probably
for HP-MS performance tuning. Unfortunately they didn't fully understand the
implications. Backing out to original approach until/unless performance becomes an issue
again.
