for us it is the standard case, that the client code is not able to 
resolve the caller class. The code making the call to the method, that 
needs the information in the end is usually in a sub loader of the 
loader in which the declaring class of the method making use of the 
information is. Not always, but usually. Thus this would be useless to us
