Tweaking JMXIntroduction so it just directly registered my beans worked just fine. The problem is there is no way to cleanly express that that's what I want done: 1) JMXIntroduction could just try to register context.getTarget(), catch NotCompliantMBeanException, and then create and register the StandardMBean. Problem is this approach ignores the @JMX.exposedInterface value -- what if the bean is Foo implements FooMBean, Bar, and @JMX.exposedInterface=Bar.class? Kind of an edge case, but not clean. 2) JMXIntroduction could try to register context.getTarget() only if @JMX.exposedInterface=null. This would be a clean solution. Problem is null is not a valid value for an annotation attribute, and the attribute type is Class, so you can't use the "" means null trick. (Hacky idea -- make it "Class exposedInterface() default void.class". The compiler accepts that.) 3) I tried adding another attribute "boolean registerDirectly() default false;" to @JMX. But the deployment of any beans where it didn't specify the attribute failed in SimpleAnnotationValidator, which makes no attempt to read default values.
