[jboss-jira] [JBoss JIRA] (AS7-5914) Clustering unit tests using Arquillian's byteman extension fail on IBM JDK

[ https://issues.jboss.org/browse/AS7-5914?page=com.atlassian.jira.plugin.s... ] Ivo Studensky updated AS7-5914: ------------------------------- Summary: Clustering unit tests using Arquillian's byteman extension fail on IBM JDK (was: Clustering unit tests using Arquillian's byteman extension fail on IBM JDK 7) Description: There are 2 tests in the clustering unit tests in the AS7 source code which are using Arquillian's byteman extension which fail when running on IBM JDK 7. Because of this it is not possible to compile AS7 with IBM JDK7 unless the unit tests are skipped by -DskipTests. Affected tests: clustering/infinispan/src/test/java/org/jboss/as/clustering/infinispan/subsystem/OperationSequencesTestCase.java clustering/jgroups/src/test/java/org/jboss/as/clustering/jgroups/subsystem/OperationSequencesTestCase.java The issue affects both IBM JDK6 and JDK7. was: There are 2 tests in the clustering unit tests in the AS7 source code which are using Arquillian's byteman extension which fail when running on IBM JDK 7.

Environment: IBM JDK was: IBM JDK 7 IBM J9 VM (build 2.6, JRE 1.7.0 Linux amd64-64 20120809_118929 (JIT enabled, AOT enabled) The reason why it is failing is that ibm jdk does not allow redefine classes in such an environment, i.e. Instrumentation#isRedefineClassesSupported() returns false. I've spent a day with trying to figure out what additional configuration ibm jdk would need to enable it, but without any success. A note regarding ibm jdk can be found in byteman documentation which says that installation an agent into a running ibm jvm does not work which is exactly what bmunit does. See https://community.jboss.org/wiki/ABytemanTutorial#how_do_i_install_the_ag... There is another option how to run bmunit in arquillian. The automatic loading of agent by arq can be inhibited and appropriate -javaagent option can be passed to a forked surefire on the command line. This can fix the issue. I will create pull reqs for it. -- This message is automatically generated by JIRA.
