[jboss-dev-forums] [Design the new POJO MicroContainer] - Re: JBREFLECT-50, determining need for setAccessible bug

A problem with the workaround of obtaining the BeanInfo using the interface the bean implements is that the IntrospectionTypeInfoFactoryImpl.getSuperClass does not return the superinterface for an interface. Obtaining a BeanInfo for an interface like java.lang.management.GarbageCollectorMXBean which extends java.lang.management.MemoryManagerMXBean fails to include the MemoryManagerMXBean properties:


  |    public void testGarbageCollectorMXBeanIface()
  |       throws Throwable
  |    {
  |       BeanInfo info = super.getBeanInfo(GarbageCollectorMXBean.class, BeanAccessMode.ALL);
  |       PropertyInfo name = info.getProperty("name");
  |       assertNotNull(name);
  |    }
  | 
  | ...
  | 
  | java.lang.IllegalArgumentException: No such property name for bean java.lang.management.GarbageCollectorMXBean available [collectionCount, collectionTime]
  | 	at org.jboss.beans.info.plugins.AbstractBeanInfo.getProperty(AbstractBeanInfo.java:147)
  | 	at org.jboss.test.beaninfo.test.PlatformMXBeanTestCase.testGarbageCollectorMXBeanIface(PlatformMXBeanTestCase.java:47)
  | 

name is a property in the MemoryManagerMXBean interface. 

Is this expected or a limitation of the current BeanInfo reflection implementation?
