Re: Feature request: method-local SourceFile attribute

I don't know if you got my first response to you, so I'm including the
pertinent part here.

It may or may not be that JPDA supports a different source file for each
method (maybe only down to each class). You would have to implement the
feature in Nice and make appropriate changes in JSwat to determine if it
will work or not.
