Unicast from within viewAccepted() callback throws exception in UNICAST ----------------------------------------------------------------------- Key: JGRP-564 URL: http://jira.jboss.com/jira/browse/JGRP-564 Project: JGroups Issue Type: Bug Reporter: Bela Ban Assigned To: Bela Ban Fix For: 2.6 Unit test is UnicastUnitTest.testUnicastMessageInCallbackExistingMember(). Swapping lines 505 and 506 in GMS fixes the issue. Stack trace is below. The issue is that - since we propagate the new view up the stack first, then down - the viewAccepted() callback gets invoked first, before UNICAST can update its view (done when the new view is propagated down the stack). We need to investigate whether swapping lines 505 and 506 breaks JGRP-347 7:45:12,375 [WARN] [Incoming Thread,x,192.168.5.2:1959] JChannel.up(): failed calling viewAccepted() in receiver java.lang.RuntimeException: java.lang.IllegalArgumentException: 192.168.5.2:1961 is not a member of the group [192.168.5.2:1959] (enabled_members=[]) at org.jgroups.tests.UnicastUnitTest$MyReceiver.viewAccepted(UnicastUnitTest.java:84) at org.jgroups.JChannel.up(JChannel.java:1099) at org.jgroups.stack.ProtocolStack.up(ProtocolStack.java:325) at org.jgroups.protocols.pbcast.STATE_TRANSFER.up(STATE_TRANSFER.java:151) at org.jgroups.protocols.FRAG2.up(FRAG2.java:197) at org.jgroups.protocols.FC.up(FC.java:414) at org.jgroups.protocols.pbcast.GMS.installView(GMS.java:505) at org.jgroups.protocols.pbcast.CoordGmsImpl.handleViewChange(CoordGmsImpl.java:449) at org.jgroups.protocols.pbcast.GMS.up(GMS.java:661) at org.jgroups.protocols.VIEW_SYNC.up(VIEW_SYNC.java:160) at org.jgroups.protocols.pbcast.STABLE.up(STABLE.java:234) at org.jgroups.protocols.UNICAST.up(UNICAST.java:263) at org.jgroups.protocols.pbcast.NAKACK.handleMessage(NAKACK.java:720) at org.jgroups.protocols.pbcast.NAKACK.up(NAKACK.java:546) at org.jgroups.protocols.BARRIER.up(BARRIER.java:122) at org.jgroups.protocols.VERIFY_SUSPECT.up(VERIFY_SUSPECT.java:167) at org.jgroups.protocols.FD.up(FD.java:322) at org.jgroups.protocols.FD_SOCK.up(FD_SOCK.java:298) at org.jgroups.protocols.MERGE2.up(MERGE2.java:145) at org.jgroups.protocols.Discovery.up(Discovery.java:247) at org.jgroups.protocols.TP$IncomingPacket.handleMyMessage(TP.java:1486) at org.jgroups.protocols.TP$IncomingPacket.run(TP.java:1435) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:885) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:907) at java.lang.Thread.run(Thread.java:619) -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
