java.lang.IllegalArgumentException: object is not an instance of declaring class

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • I have a trace advice that is put on a cache advice. This works fine (enter/exit-trace on my cache method when it is invoked) as long as the cache advice doesn't implement an interface. When it does I get the following stack trace: Exception in thread "main" org.springframework.aop.AopInvocationException: Mismatch on arguments to advice method [public java.lang.Object se.jayway.cache.MethodSignatureCacheAdvice.cache(org.aspectj.lang.ProceedingJoinPoint) throws java.lang.Throwable]; pointcut expression
