The reinstall may coerce some missing files to be properly installed. It doesn't fix the checkVersions warning. On inspecting the source I find the script. It claims to be part of the Linux port of the jdk and not from the sun sources. It is the debian/rules files that deletes it.
To make the story short, after unintalling and reinstalling my patched version *or* the current version in slink, I am no longer able to build my java programs. The compiler cannot find the libawt.so library. I don't think it is hard to fix this. I'll look at it when I return home tonight. Cheers.
