JGroups ClassCastException joining node in dist mode ---------------------------------------------------- Key: ISPN-2760 URL: https://issues.jboss.org/browse/ISPN-2760 Project: Infinispan Issue Type: Bug Components: Distributed Cache Affects Versions: 5.2.0.CR3 Reporter: Christopher Wong Assignee: Mircea Markus Attachments: infinispan.cfg.xml I'm seeing exceptions in my application when I try to start a second node to join the cluster. The cache is for the Lucene directory hooked up under Hibernate Search. These errors did not occur under 5.2.0.CR1, 5.2.0.CR2 nor Galder's build that fixes ISPN-2723 (https://github.com/galderz/infinispan/tree/t_2723). The first node has these exceptions: 01-25-2013 13:51:40 WARN MPING protocols.MPING: group_addr (HibernateSearch-Infinispan-cluster-MT) or cluster_name of header (null) is null; passing up discovery request from 41089a5d-fe86-4679-6606-428ad1781501, but this should not be the case 01-25-2013 13:51:40 ERROR MPING protocols.MPING: failed receiving packet (from /127.0.0.1:46655) java.lang.ClassCastException: org.jgroups.protocols.relay.SiteUUID cannot be cast to org.jgroups.PhysicalAddress at org.jgroups.protocols.Discovery.up(Discovery.java:391) at org.jgroups.protocols.MPING.up(MPING.java:179) at org.jgroups.protocols.MPING.run(MPING.java:330) at java.lang.Thread.run(Thread.java:662) The joining node has these exceptions: 01-25-2013 13:52:02 ERROR MPING : failed receiving packet (from /127.0.0.1:46655) java.lang.RuntimeException: class for magic number 1151 not found at org.jgroups.util.Util.readOtherAddress(Util.java:849) at org.jgroups.util.Util.readAddress(Util.java:813) at org.jgroups.util.Util.readAddresses(Util.java:898) at org.jgroups.protocols.PingData.readFrom(PingData.java:162) at org.jgroups.util.Util.readStreamable(Util.java:938) at org.jgroups.protocols.PingHeader.readFrom(PingHeader.java:88) at org.jgroups.Message.readHeader(Message.java:902) at org.jgroups.Message.readFrom(Message.java:785) at org.jgroups.protocols.MPING.run(MPING.java:329) at java.lang.Thread.run(Thread.java:662)
