JBoss development, A new message was posted in the thread "Security problems with org.jboss.test:jboss-test 1.1.5.GA": http://community.jboss.org/message/530617#530617 Author : Flavia Rainone Profile : http://community.jboss.org/people/flavia.rainone@jboss.com Message: -------------------------------------------------------------- You're right! Taking a better look, I found this:   public class AOPTestDelegate extends AbstractTestDelegate {     public void tearDown() throws Exception     {        String deployedByClassLoader = (String)systemProps.get(EclipseTestTransformer.CLASSLOADER_DEPLOYED_XML);        if (deployedByClassLoader != null)        {           URL url = Thread.currentThread().getContextClassLoader().getResource(deployedByClassLoader);           AspectXmlLoader.undeployXML(url);        }     }     }   AbstractTestDelegate.setUpSecurity defines a SecurityManager, and AbstractTestDelegate.tearDownSecurity should set the SecurityManager as null. This is not happening, because AbstractTestDelegate.tearDown is overwritten and the call to super.tearDown is commented out.   Uncomenting this call took me to:   Testcase: testBasic took 1.531 sec         Caused an ERROR access denied (java.lang.RuntimePermission setSecurityManager) java.security.AccessControlException: access denied (java.lang.RuntimePermission setSecurityManager)         at java.security.AccessControlContext.checkPermission(AccessControlContext.java:323)         at java.security.AccessController.checkPermission(AccessController.java:546)         at java.lang.SecurityManager.checkPermission(SecurityManager.java:532)         at java.lang.System.setSecurityManager0(System.java:272)         at java.lang.System.setSecurityManager(System.java:263)         at org.jboss.test.AbstractTestDelegate.tearDownSecurity(AbstractTestDelegate.java:195)         at org.jboss.test.AbstractTestDelegate.tearDown(AbstractTestDelegate.java:142)         at org.jboss.test.aop.AOPTestDelegate.tearDown(AOPTestDelegate.java:66)         at org.jboss.test.AbstractTestSetup.tearDown(AbstractTestSetup.java:73)         at org.jboss.test.AbstractTestCaseWithSetup.tearDown(AbstractTestCaseWithSetup.java:112)   -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/530617#530617
