[jboss-as7-dev] Running single tests

Hi all, I'm having a problem with running single tests on jboss-as/master. If I run all the "basic" integration tests (via ./integration-tests.sh test -Dts.basic), everything works fine. But if when I run a certain test only (/integration-tests.sh test -Dts.basic -Dtest=NegativeValidationTestCase), that one will fail. The log says: org.jboss.msc.service.DuplicateServiceException: Service jboss.connector.connection-factory.java:jboss/exported/bv/VCF is already registered (See http://pastebin.com/DkrwVgU5 for the complete stack trace). IIUC this factory is registered by this test itself, but somehow it fails to be properly removed/cleaned up when only this single test is run. Does anyone have an idea what's the cause for this and how it can be avoided? Thanks a lot, --Gunnar
