Tom Elrod commented on JBREM-553:
----------------------------------
Am having no success in reproducing deadlock. Have updated the test cases (will explain
test scenario in detail below) to use ssl socket and have client on both client and
server. Can you take a look at test cases to see if there is something else I am
missing?
test classes:
org.jboss.test.remoting.detection.multicast.deadlock.DeadlockTestCase
org.jboss.test.remoting.detection.multicast.deadlock.MulticastDetectorClient
org.jboss.test.remoting.detection.multicast.deadlock.MulticastDetectorServer
Test scenario:
MulticastDetectorServer - will setup with multicast detector and connector. The connector
will use sslsocket transport and CLIENT_AUTH_MODE_WANT. The handler for the connector
will expect any invocation calls to contain locator url for connector running within the
client (MulticastDetectorClient). When it gets the locator url, will create and run a
ServerClient, which will take the locator url and create a remoting client and make an
invocation on that connector and then disconnect.
MulticastDetectorClient - will setup with multicast detector and will then force detection
which will return the locator url for the MulticastDetectorServer. It will then create a
connector itself and then create a client that calls on the MulticastDetector server
connector (via locator it discovered) and pass the locator url for the connector just
created on the client. Then waits 30 seconds and disconnects.
DeadlockTestCase - driver class for both client and server (so will be local calls instead
of remote).
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:
