All classes generated from Scala sources, have a classfile attribute that tells the name of the source they originate from. Except for those compiled from Java (we have a couple, such as BoxesRunTime). The end-result is that you can't really debug or set breakpoints in these files.

By default, javac sets this attribute for all classfiles it generates.

I guess this is unintentional, but it is pretty annoying in the debugger.

Adding debug="true" to the various javac tasks in build.xml will remedy this.

FYI "lines,vars,source" is the default.
