Description of problem: Running JBossWS testsuite against EAP 6.4.6.CP.CR2, there is a constant set of tests failing on some RHEL6 x86 nodes with IBM Java 8 Version-Release number of selected component (if applicable): JBossWS TS 4.3.6.Final-redhat-1 How reproducible: on almost all nodes in QA jenkins, never locally on Fedora Steps to Reproduce: 1. run http://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/EAP6/view/EAP6-WS/job/eap-6x-jbossws-testsuite-smoke/ with proper parameters Actual results: 79 failed tests http://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/EAP6/view/EAP6-WS/job/eap-6x-jbossws-testsuite-smoke/389/testReport/ Most of them failed with cause "Caused by: java.net.ConnectException: Connection refused" either on client or server side. Expected results: all tests pass Additional info: I will try to investigate more, especially to determine if it is environment issue, testsuite issue or issue with JDK.
