java, jdk, blackdown & redhat

[Craig Miller <craig_(_at_)_millerfam_(_dot_)_net>]

After perusing the mailing list archives a bit, the most common suggestion
for a JDK is to run blackdown along with the redhat emulation environment.
I am wondering...

Why run OpenBSD if I have to run a redhat emulator in order to run my
servers?  Seriously, I am wondering if there is a benefit to running it this
way over running blackdown in its native redhat environment.

Thanks,
