Sergey Mashkov commented on BCEL-170:
-------------------------------------

What do you expect to get? As far as I understand result should be:

{noformat}
Ret: net.sf.sample.SampleReturn
Prm: net.sf.sample.SampleMethodParameter
{noformat}

                
> Type.getArgumentTypes() throws ClassFormatException: Invalid method 
> signature: >;)
