Brian Stansberry commented on AS7-5418:
---------------------------------------
The :read-resource text description for such an attribute should include something like
"May be 'undefined' if the VM does not support this property." Documents
why what seems like a simple boolean or something may not have a value.
I believe I handled this properly in at least some cases, so have a look and make the
handling (e.g. the text description) consistent.
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)
Environment: FreeBSD, OpenJDK 1.6
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)
