mod_cluster with Undertow throws java.lang.IllegalArgumentException on IPv6 system ---------------------------------------------------------------------------------- Key: MODCLUSTER-384 URL: https://issues.jboss.org/browse/MODCLUSTER-384 Project: mod_cluster Issue Type: Bug Affects Versions: 1.3.0.Alpha2 Environment: both Oracle JDK7 and OpenJDK7, RHEL6, both pure-IPv6 and dualstack Reporter: Michal Babacek Assignee: Radoslav Husar Attachments: error_log.zip, jboss-eap-8.0-2.server.log.zip, jboss-eap-8.0.server.log.zip Guys, something is amiss with MCMP parsing and/or Undertow integration on IPv6 systems. There is this test: # configure and start *balancer*:httpd, *worker1*:jboss-eap-8.0, *worker2*:jboss-eap-8.0-2 (ignore this weird `jboss-eap-8`, it's just WildFly 8.0.0.Final-SNAPSHOT) # verify that application context is accessible via balancer # make a request and remember which worker processed it # commence a clean shutdown on that worker # make another request and make sure the other worker takes care of it # start that worker stopped in step 4. # wait till it's present on the mod_cluster manager console # stop that other worker that handled the request in step 5. # make a request and verify that someone is gonna take care of it The aforementioned test {color:green}passes{color} with the exactly same bits in an IPv4 environment with no problems whatsoever. On an IPv6 system, setup collapses with this in the server log (attached server log for both workers: [^jboss-eap-8.0.server.log.zip], [^jboss-eap-8.0-2.server.log.zip] ) {noformat} 2014-01-30 09:00:41,279 ERROR [org.jboss.modcluster] (UndertowEventHandlerAdapter -
