Hi,
after some more testing, it seems that the NullPointerException occurs
everytime when an annotated method has one or more parameters (annotating the
parameter or not seems to be irrelevant).
Removing the method-parameter directly prevents Shiro throwing the
NullPointerException...
Is this an known bug of AspectJ Shiro authorization package or should I fill a
JIRA ticket?
