[jboss-user] [JBoss Remoting] - ClassCastException under heavy load

Markus Falk [http://community.jboss.org/people/cornhoolio22] created the discussion "ClassCastException under heavy load" To view the discussion, visit: http://community.jboss.org/message/584322#584322 -------------------------------------------------------------- Hi, I'm looking at the same problems as described here: http://community.jboss.org/thread/111357 http://community.jboss.org/thread/111357 Under heavy load ClassCastExceptions are thrown. The situation: 2 ears on one server (4.2.3, jbm 1.4.5, jboss-remoting 2.2.3.SP1) calling the same ejb on another appserver (same configuration) with the same value object. When producing heavy load on ear 1 (10 threads parallel as clients) and then calling one time ear 2, a ClassCastException is thrown. Will list it below the text. I found a fix for the problem in https://issues.jboss.org/browse/JBREM-900 https://issues.jboss.org/browse/JBREM-900. This fix seems not to be in the 2.2.3SP1 nor in the 2.2.3.SP3 release. I also read in the JIRA ( http://community.jboss.org/message/583757#583757 http://community.jboss.org/message/583757) that there will be a 2.2.3SP4 release (hope soon ;-) ) and found a preversion from Ron ( https://issues.jboss.org/browse/JBREM-1144 https://issues.jboss.org/browse/JBREM-1144). But the fix is also not in there (the test fails again). When I use the 2.4.0.SP1 remoting version, the test succeeds. But the Messaging System is not able to work with this version, because of changes in the Client class (the connect method params were changed). Is it possible, to release the Bugfix described in https://issues.jboss.org/browse/JBREM-900 https://issues.jboss.org/browse/JBREM-900 with the 2.2.3.SP4 release?
