Has this been tested under Cygwin?

I'm not sure whether exec works as expected there and cannot test it,
that's why I've kept away from that patch.

changes things a bit.  In the old version jikes.class.path would be
left unset if the environment variable JIKESPATH was unset (and you
are not on MacOS X).  Now this property will be always defined, but
may get an empty value.

There certainly is a difference between a property that is not set and
an empty one (see if/unless attributes) and the jikes compiler adapter
behaves differently as well:

        String jikesPath = System.getProperty("jikes.class.path");
        if (jikesPath != null) {
            classpath.append(new Path(project, jikesPath));

which may lead to adding an empty entry to the classpath before
invoking jikes.

Could you please revert at least this last part of the patch?
