What I'm looking at is a good way to perhaps _build_ with Java here, but allow OOo to run on non-Java-enabled systems and Java-enabled systems at the same time. That's not exactly easy though.
The OOo build require the jvm setup, but will work without java. This should be doable.
For the time being, if you'd like to use Java, I'd suggest grabbing the SRPM and removing the "--disable-java" from the ./configure options, and also commenting out all the "handle-no-solar-java" patches.
