The method which provokes the Exception is
<aspects.PrinterAspect: void proceed$0(java.lang.String)>

and is generated from my advice

       void around(Printing p) {
               System.out.println();
               System.out.println("\t-------------------------------------------");
               System.out.println("\t*** before Printing *** "+thisJoinPoint);
               System.out.println("\tp.test="+p.test);
               System.out.println("\tClass of Joinpoint : "+p.getClass());
               System.out.println("\tSignature :
"+thisJoinPoint.getSignature());
               System.out.println("\t-------------------------------------------");

               proceed(p);

               System.out.println("\t-------------------------------------------");
               System.out.println("\t*** after Printing *** "+thisJoinPoint);
               System.out.println("\t-------------------------------------------");
               System.out.println();
       }

This advice has no pointcut as I set this pointut during compilation
to all pointcuts of the joinpoint Printing (which is the argument).
If there is no pointcut for Printing, i create the never matching
pointcut mentioned above. This I have to do as the advice defines a
formal parameter. If this parameter is not be bound via this(),
target() or args() an error is generated during checking the AST.

In addition to manipulating the pointcut expression of the advice I
add a statement to the advice body. But i do this in the frontend
before the jimple code is generated.

Greetings,
Thomas
