I'm not sure "resurrecting" (which actually means adding functionality
which has been gone for quite some time now) is good, since it adds to
However, there have been recurring requests of having more control of
debug vs release builds, and I think we need to address them in some
way. As you say, one dimension is asking wether java or native (or both)
should be compiled as debug. Another typical request is to separate
hotspot debug level from the rest of the JDK (this goes both ways).
Also, debugging can come in several "levels", depending on what tradeoff
between speed/similarity to release vs amount of debug support you need.
Maybe it should be possible to set debugging level per module?
