Well, that's very interesting but it wasn't this code that was missing,
rather a significant swathe of the core JDK runtime classes.

No, indeed. And I wouldn't expect it to be anything other than Java
sources since the purpose of src.zip is merely to provide a Java
debugger with the sources of the Java bytecode included in the core JDK
runtime (if we were ever to get to the point where gdb can debug Java
and C++ well, I might then start clamouring for the hotspot sources to
be included :-). But I did expect src.zip to contain all, or very nearly
all, of the core JDK runtime sources.

I agree this is not really a module system issue which is why I posted
to build-dev. I also posted to the Jigsaw dev list because it seemed to
relate to the re-organization which resulted from introduction of the
module system and thought you might be able to short-circuit the enquiry.
Anyway, I'm quite happy so long as Red Hat can produce releases which
allow the full core JDK runtime to be debugged from a Java debugger.
