--------------------------------------

Have you tried method.getAnnotations()?  It would raise an exception if one of the annotation types is not found.  getAvailableAnnotations() simple ignores an unknown annotation and returns null.

> We have developed a jUnit testcase that test the annotation for an existing method.
> Our own classloader first loads the class that contains the method and then tries to get any available annotations.
> Our annotated method looks like this, using our own NotificationEmitter.class.
> @NotificationEmitter(description = "Notifies xxx", type = xxx.class)
> public void method() {
> ...
> }
> Sometimes when we call method.getAvailableAnnotations(); it returns 
> When it fails seems to be very nondeterministic.
> Any help would be appreciated.
