It is this very thing which causes me to suggest a Debian-based distro
like Ubuntu.  While my favorite, most "useable" distro is still SuSE,
they do not change package versions almost ever.  Security and
bug-fixes come as updates within the same version.  While in a
corporate environment this can be a positive thing, as a desktop I
want to have the ability to upgrade the software from time to time.

This part confuses me.  What does Java being "in a state of flux"
mean? Please don't take this wrong, but compared to Fedora, Java is
quite stable.

In my googling it looks like RH's kernel/glibc tinkering is what
caused the need for LD_ASSUME_KERNEL with Java in the first place.
Each article I have read states something like "In RedHat 7.1, RH
introduced this oddity" or "in RedHat 9 you may experience xyz
behavior" and the solution is to set LD_ASSUME_KERNEL to something
other than the supposed version.

google: LD_ASSUME_KERNEL java

I've never had to set this variable and run Java on quite a few
platforms.  However, I have compared the RH Kernel tree with
Kernel.org and SuSE's source tree and found Fedora to be quite
different (like whole sections and symbol-sets missing or rewritten).
With their efforts to backfill their 2.4 kernels with 2.6
functionality it seems they've done some pretty funky things.
