Not quite :-)

Last summer someone managed to install the OF Java package under OSX on
Octave-3.6.x (search the ML, I think it was Pascal Dupuis).

However, in 3.8.0 the OF Java package cannot be installed anymore, as Java
support became a core Octave feature rather than an add-on. IOW, Java has to
be built in during building Octave itself. TTBOMK no one has succeeded doing
that for OSX yet. 
Maybe you can try building Octave from scratch and include Java along the
way outlined in the thread mentioned above.
Other than that, I'm afraid you're SOL.
