Using an IDE to work on the Java library

[Andrew Haley]

Sorry for what must seem like a newbie question...

I've done almost all of my work on HotSpot, and have very little
experience trying to use an IDE to work on the Java library.  Eclipse
is fine when working on libraries outdie the JDK itself, but seems to
want to look inside src.zip for its sources when debugging.  It would
be really nice to be able to see (and edit) the real Java source files
in jdk/java.base/.

I suppose there must be some way to create a Project for an IDE, so
that debugging the standard library is easy.  Is there some advice
around somewhere?  What do people do?

Thanks,
