> 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
