@JMX on a bootstrap service

brian.stansberry Aug 13, 2008 6:21 PM

I'm trying to apply an @JMX annotation to a bean that's deployed as part of the bootstrap. The bean deploys fine, and I can see it in the jmx-console, but during shutdown I'm getting a CNFE. Any ideas why?

The deployment:

<?xml version="1.0" encoding="UTF-8"?>

<deployment xmlns="urn:jboss:bean-deployer:2.0">

 <classloader><inject bean="bindings-classloader:0.0.0"/></classloader>

 <classloader name="bindings-classloader" xmlns="urn:jboss:classloader:1.0" export-all="NON_EMPTY" import-all="true">
 <root>${jboss.lib.url}/jboss-bindingservice.jar</root>
 </classloader>

 <bean name="ServiceBindingManager" class="org.jboss.services.binding.ServiceBindingManager">

 <annotation>@org.jboss.aop.microcontainer.aspects.jmx.JMX(name="jboss.system:service=ServiceBindingManager",exposedInterface=org.jboss.services.binding.ServiceBindingManagerMBean.class,registerDirectly=true)</annotation>

 <constructor>
 <!-- The set of bindings to use for this server -->
 <parameter>${jboss.service.binding.set:ports-default}</parameter>

The shutdown logging:

It's a bug: https://jira.jboss.org/jira/browse/JBMICROCONT-339
actually there's more than one in there. :-(

I've fixed this and also removed the potential memory leak
by adding a CachingAnnotationMetaData interface.

It's not as optimal as I would like because of the property annotations.
In that case the annotation gets added to both the getter and setter,
so when we remove the annoation for the getter we loose track of the
annotation when we want to remove the setter, so we have to reconstruct it.

If this was a way to optimize that case, the code in KernelScopeInfo could be
Annotation annotationInstance = null; if (annotation instanceof CachingAnnotationMetaData) annotationInstance = ((CachingAnnotationMetaData) annotation).removeAnnotation(); - if (annotationInstance == null) + else annotationInstance = annotation.getAnnotationInstance(classloader); // Null means we never constructed it in the first place if (annotationInstance != null) mutable.removeAnnotation(annotationInstance.annotationType());
