[jboss-jira] [JBoss JIRA] Commented: (AS7-970) Seam3 booking example hangs after a few requests on AS7

[Stuart Douglas (JIRA)]

    [ https://issues.jboss.org/browse/AS7-970?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12607692#comment-12607692 ] 

Stuart Douglas commented on AS7-970:
------------------------------------

Just looking at the interceptor is looks like tryLock() is being called multiple times but unlock() is only called once. We need to check if the lock is already held before calling tryLock.

There is also the possibility in many places for an exception to leave the lock locked.
