LoginContext cannot load login modules in certain scenarios when EAP server is started by Arquillian ----------------------------------------------------------------------------------------------------- Key: ARQ-1820 URL: https://issues.jboss.org/browse/ARQ-1820 Project: Arquillian Issue Type: Bug Reporter: Miroslav Novak Priority: Major There is problem with classloading when EAP 6.3.0.ER9 server is started by Arquillian. Problem was hit in following test scenario: - Start two EAP 6.3.0.ER9 servers - HornetQ is configured in collocated HA topology with shared store (EAP servers contains HornetQ backup for each other - so there are 2 live/backup pairs) - Start producer which sends messages to "jms/queue/testQueue0" to first EAP server - Start consumer which receives messages from "jms/queue/testQueue0" to first EAP server - Kill -9 "first EAP server" - Producer and consumer failovers to backup Problem: When producer and consumer failovers to backup then it fails with: {code} 13:58:40,146 Thread-2

at java.lang.Thread.run(Thread.java:722) [rt.jar:1.7.0_15] {code} It failed because it was not authenticated on second EAP server. When debugging the problem I figured that root cause for this failure is that javax.security.auth.login.LoginContext.invoke(String methodName):746 is using reflection to load class - org.jboss.as.security.RealmDirectLoginModule which was not found in provided classloader: {code}Class c = Class.forName(moduleStack[i].entry.getLoginModuleName(), true, contextClassLoader);{code} When I try the same test scenario manually then producer and consumer failovers without problem (=authenticates). Is there a way how EAP 6 classloader can be influenced by Arquillian?
