Where we again are in your broken system config with stable being on
highest priio but your system being (almost) completely unstable (even
base-files got upgraded), but anyways...

Yes, seems so. But a dependency on gcj-4.4-jre will not force you anything,
gij,gcj etc. can still point to anything, gcj-4.4-jre just brings you an
empty package which brings you gcj-4.4-jre-headless, which gives you gij-4.4,
gcj-4.4 via it's dependencies, not "gij" or "gcj" or whatever your "java" might
point to.

I don't know what the problem is, but I think you are at least not wrong. The question
is what to add where to make it safe, maybe doko can help here?
Except maybe a Conflicts against gcj/gij << version-libreoffice-gcj-build-with,
but that's error-prone, too I think...
