Hello, after I switched to using Eclipse 3.2 with JBossIDE2.0Beta1 (from Eclipse 3.1.2 with JBossIDE1.5) I get the following errormessages in my console: 10:54:07,505 WARN [UDP] discarded message from different group (Tomcat-Cluster). Sender was 127.0.0.1:2082 10:54:19,098 WARN [UDP] discarded message from different group (DefaultPartition). Sender was 127.0.0.1:2070 (additional data: 15 bytes) 10:54:26,770 WARN [UDP] discarded message from different group (Tomcat-Cluster). Sender was 127.0.0.1:2082 It's possible to get rid of it using the hint from http://www.jboss.com/index.html?module=bb&op=viewtopic&t=60110, but I don't know why that is necessary. I didn't change the JBoss configuration (which is the configuration of a cluster with no other members). So did the old JBossIDE suppress the warning by itself or is there really an issue with the new version in regard to jgroups?
