             Summary: Resource description for platform mbean properties that throw UnsupportedOperationException should say nillable="true"
                 Key: AS7-5418
                 URL: https://issues.jboss.org/browse/AS7-5418
             Project: Application Server 7
          Issue Type: Bug
          Components: Domain Management
    Affects Versions: 7.1.2.Final (EAP)
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
            Priority: Minor


Some platform mbean getters are documented to throw a UOE on some VMs. The read-resource handler will catch the UOE and leave the attribute undefined, but the description says it's not nillable.

Specifically, PlatformMBeanDescriptions.getThreadingResource()'s THREAD_CPU_TIME_ENABLED attribute, although there may well be others.

This leads to this unit test failure on jvms where the UOE is thrown:

failure message="thread-cpu-time-enabled is undefined" 
 type="junit.framework.AssertionFailedError">junit.fra mework.AssertionFailedError: thread-cpu-time-enabled is undefined
          at junit.framework.Assert.fail(Assert.java:50)
          at junit.framework.Assert.assertTrue(Assert.java:20)
