      How to run the test locally:

      git clone git://git.app.eng.bos.redhat.com/jbossqe/eap-tests-hornetq.git
cd eap-tests-hornetq/scripts/
git checkout refactoring_modules
groovy -DEAP_VERSION=7.0.0.ER6 PrepareServers7.groovy

export JBOSS_HOME_2=$WORKSPACE/server2/jboss-eap
export JBOSS_HOME_3=$WORKSPACE/server3/jboss-eap
export JBOSS_HOME_4=$WORKSPACE/server4/jboss-eap
cd ../jboss-hornetq-testsuite/
mvn clean test -Dtest=CliReloadTest#reloadServerOOMTest  -DfailIfNoTests=false  -Deap=7x  | tee log

After the test is started:
Start Visualvm and check memory grow of EAP server.

      There is regression against EAP 7.0.0.ER5. if server is continuously reloaded then there is out of memory java.lang.OutOfMemoryError: GC overhead limit exceeded.

      I've created heap dump at the beginning of the test and then after 20 min so it can be compared which instances are growing. Heap dumps can be downloaded by:

      scp jbossqa@10.40.4.81:/home/jbossqa/tmp/oom-reload.zip . #password: jbossqa

      Issue is under investigation. I tried to replace Artemis jars in EAP 7.0.0.ER6 by jars from EAP 7.0.0.ER5 and did not see any memory leaks.
