some questions about Java ports

[Mikhail Teterin]

= The defined/undefined logic allows for more flexbility IMHO.

Right -- and the bsd.port.mk cares only for this one bit of information.
Then the included bsd.java.mk looks more closely at what is actually
defined and uses that.

= Are you advocating for a re-design of the Java support in bsd.java.mk?

I'd like it to remain legal to just use USE_JAVA=version -- instead of
having to use extra variables.

I don't think, the javac compilation needs to be explicitly described in
build.xml. Hence there ought to be some standard property somewhere --
not unlike CFLAGS settings in ours and GNU makes. Unfortunately, I have
no idea, where or what it is, and am only guessing here...

javac has about a dozen of options. -g:xxx, -Jxxx, -encoding, -target,
-Xxxx...

= the MAKE_ENV/JAVA_HOME issue as well.

See the attached dummy port. Note, it already has the .extract cookie
created in its fake "work". Try running `make -V CONFIGURE_ENV' first --
the JH will be part of it nicely.

Then run `make configure' and see it report an empty JH (and JAVA_HOME).
