The org.jboss.test.jbossmx.compliance.objectname.MalformedTestCase testMalformed fails when using the Sun 1.5.0_08 JVM. A bug report was opened for this (http://jira.jboss.com/jira/browse/JBAS-3549) but was closed (won't fix): "We can't fix this (short of removing the test). That is an invalid ObjectName, but Sun's class (unlike JBoss's version) does not spot the problem." I was told I couldn't ask questions about the bug in the bug report, and to ask them here. Here are the questions I tried to ask before: -Could you please explain this issue a little bit more? -Why does JBoss have separate versions of Sun's classes? -This test usually passes on the 1.4.2 JVM, is this test only meant to be run on a 1.4.2 JVM?
