deadlock when disconnecting
---------------------------
Key: JBREM-553
URL: http://jira.jboss.com/jira/browse/JBREM-553
Project: JBoss Remoting
Issue Type: Bug
Security Level: Public (Everyone can see)
Affects Versions: 2.0.0.Beta2 (Boon)
Reporter: John Mazzitelli
Assigned To: Tom Elrod
Fix For: 2.0.0.CR1 (Boon)
I am seeing a deadlock in my test suite. It happens everytime. I haven't finished
looking at all the data, but I'm submitting this JIRA now because I only started
seeing this after building a new remoting jar from HEAD and installing it. I do not
believe any changes that I did caused this (I haven't changed much if any code in my
own stuff - though I will test this by switching out to an older remoting jar to see what
happens).
Here's the two threads that deadlocked on java.util.LinkedList<E> (id=2271:
