[jboss-jira] [JBoss JIRA] Closed: (JBREM-553) deadlock when disconnecting

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: Thread [Thread-3562] (Suspended) owns: java.io.BufferedInputStream (id=2299) owns: java.util.LinkedList<E> (id=2271)
