--------------------------------------
Assignee: John D. Ament
Fix Version/s: 1.7.2
> Incorrect exception handling in DynamicMBeanWrapper.invoke()
> ------------------------------------------------------------
>
> Key: DELTASPIKE-1207
> URL: https://issues.apache.org/jira/browse/DELTASPIKE-1207
> Project: DeltaSpike
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.7.1
> Reporter: Falko Modler
> Assignee: John D. Ament
> Fix For: 1.7.2
>
>
> {{DynamicMBeanWrapper.invoke(String, Object[], String[])}} just re-throws any
> exception as a {{RuntimeException}}.
> This makes it impossible for a client to determine the specific exception
> which might have been thrown on purpose by the MBean method. See also:
> {code:java|title=JavaDoc of javax.management.DynamicMBean.invoke(String,
> Object[], String[])}
> ...
> * @exception MBeanException Wraps a <CODE>java.lang.Exception</CODE>
> thrown by the MBean's invoked method.
> * @exception ReflectionException Wraps a
> <CODE>java.lang.Exception</CODE> thrown while trying to invoke the method
> */
> public Object invoke(String actionName, Object params[], String
> signature[])
> throws MBeanException, ReflectionException ;
> {code}
> So the correct approach is to handle {{InvocationTargetException}}
> specifically by wrapping it's *cause* in a {{MBeanException}} and throwing
> that {{MBeanException}}.
> All other exceptions should be wrapped in a {{ReflectionException}}.
> PS: I filed DELTASPIKE-984 some time ago which led to a slight improvement of
> the very same {{invoke}} method but obviously my suggestions regarding
> {{MBeanException}} haven't been considered (I don't know why).
