BZ #18: Doesn't raise expected exception during MethodInterceptor.invoke

Status fields:

If an exception is thrown during the invocation of MethodInterceptor.invoke
(which happens in calls on Proxy), the exact exception should be raised instead
of a generic UndeclaredThrowableException.
This problems can be seen in spring junit tests and is not reproduced with jamvm
nor Sun jdk.
