Resource description for platform mbean properties that throw UnsupportedOperationException should say nillable="true" ---------------------------------------------------------------------------------------------------------------------- Key: WFCORE-406 URL: https://issues.jboss.org/browse/WFCORE-406 Project: WildFly Core Issue Type: Bug Components: Domain Management Environment: FreeBSD, OpenJDK 1.6 Reporter: Brian Stansberry Priority: Minor Fix For: 3.0.0.Alpha7 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) at org.jboss.as.platform.mbean.PlatformMBeanResourceUnitTestCase.validateResource(PlatformMBeanResourceUn itTestCase.java:595) at org.jboss.as.platform.mbean.PlatformMBeanResourceUnitTestCase.basicResourceTest(PlatformMBeanResourceUnitTestCase.java:563) at org.jboss.as.platform.mbean.PlatformMBeanResourceUnitTestCase.testThreadingMXBean(PlatformMBeanResourceUnitTestCase.java:340)
