-Do you receive a ''StackOverflowError''? This is a common pitfall in AspectJ (see [[http://www.eclipse.org/aspectj/doc/released/faq.html#q:infiniterecursion|the FAQ entry]]). An infinite loop occurs because there is a matching join point inside of the control-flow of the advice body, which causes a new invocation of the advice body, which causes a new join point and so on.

-To discover the root of the infinite loop, consider the difference between this advice body and the one from the previous exercise. Solve the problem by making the pointcut more restrictive: it should exclude join points in the control flow of the advice execution.

Another clue is in the "official" description of  [[http://java.sun.com/docs/books/jls/third_edition/html/expressions.html#39990|Java String Concatenation]].
