Summary: In aix platform, A TCK case can't pass.

Initial Comment:
Description:
The TCK case is com/sun/ts/tests/jmx/api/javax/management/openmbean/ArrayTypeTest/ArrayTypeTest.java#testIsValue_from_standalone and it only failed in AIX platform.

Analysis:
The reason to casue the case failed is that in javax.management.openmbean.ArrayType.java of mx4j, the funciton  
public boolean isValue(Object object)
{
     if (object == null || !object.getClass().isArray())
      {
	      return false;
      }

      if (elementType instanceof SimpleType)
      {
	      return getClassName().equals(object.getClass().getName());
      }

      if (elementType instanceof TabularType || elementType instanceof CompositeType)
      {

	     try
         {
	         Class elementClass = Thread.currentThread().getContextClassLoader().loadClass(getClassName());
            
	         if (elementClass.isAssignableFrom(object.getClass()))
            {
                 return checkElements((Object[]) object, dimension);
            }
         }
         catch (ClassNotFoundException x)
         {
             return false;
         }
      }
      return false;
}

when without -Xdebug to JVM,  "Class elementClass = Thread.currentThread().getContextClassLoader().loadClass(getClassName())" will throw ClassNotFoundException. The return value of Thread.currentThread().getContextClassLoader() is sun.misc.Launcher$AppClassLoader and the value of getClassName() is [Ljavax.management.openmbean.CompositeData;
the object  parameter is an instance of  javax.management.openmbean.CompositeDataSupport.

when with -Xdebug to JVM,the value is same but no exception.

having or not the -Xdebug option on the IBM JVM.
I fail to see how this can be an MX4J bug.
