For the tests above, method deleteRecursively() does not delete test module directories properly, part of module directory remain in JBOSS_HOME/modules after test completion.

Example: JBOSS_HOME/modules/org/jboss/test is left behind for WeldModuleDeploymentTestCase, in that case the testModuleRoot is org/jboss/test/weldModule
