[ https://issues.jboss.org/browse/JBTM-1602?page=com.atlassian.jira.plugin.... ] Mark Little commented on JBTM-1602: ----------------------------------- I just noticed this change in the code and tracked it back to github (no JIRA associated with it, so I couldn't see what the issue was): try { Object syncObject = ((BasicAction.Current() == null) ? getMutex() : BasicAction.Current()); synchronized (this) { synchronized (getMutex()) { synchronized (syncObject) { I'm not sure why this change is in here, but need to check because it doesn't look right. Ignoring the fact that we now have 3 locks being acquired before the actual locksHeld lock, we're also potentially acquiring the same lock twice (syncObject could be getMutex())! -- This message is automatically generated by JIRA.
