Hi there,
using Shiro along with "JBoss RESTeasy" for fast rest-based
web-application development I'm running into some mysterious
NullPointerExceptions :-/
Example-Code:
----------
@POST
@Path("/{contactType}")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.APPLICATION_JSON)
@RequiresUser
public static Response createContact(@PathParam("contactType") String
contactType, String request)
{
// do something
}
----------
Sending an POST-Request to the site produces the following Exception:
----------
[...]
Caused by: java.lang.NullPointerException

Looking into org.apache.shiro.aop.DefaultAnnotationResolver at line 62:
return annotation == null ? mi.getThis().getClass().getAnnotation(clazz)
: annotation;
So the only possible source of the NullPointer seems to be
"mi.getThis()" for me...
Any suggestions how to avoid and/or solve this?
