FreeBSD is a superior system for the causal system administration tasks
that I need to perform. The operating system is rev'd as a single,
integrated source tree ("/usr/src") shared with a wide community of
users who ensure that it is robust and "battle-tested". With the
combination of the ports system, almost any open source package that I
care to use can be downloaded, compiled, dependency checked, and
installed. Being able to use a system for which *all* of the source
that runs can be quickly inspected proves to be a superior
differentiating resource.

It's fast enough, as my work is more research than production. If I
really wanted performance, I would probably go with OpenSolaris, since I
would expect that SUNW would have tuned things well on their operating
system. Surprisingly, this has not always been the case, especially for
solaris-ia32, but from anecdotal evidence (i.e. no benchmarks) the
performance of Java 1.6 on solaris-ia32 seems quite good.

I suspect that with the further optimization to multithreading within
the kernel in the upcoming FreeBSD 7 release, things will only get
better for performance.

Certainly. And when FreeBSD java does have problems, you can get out
and push easily. The freebsd-java mailing list is especially responsive
resource when intelligent bug reports are filed.

Sure, FreeBSD Java is secure as much as the base Java libraries are
secure. If I cared about security for an application, I would isolate
the necessary JVM in a FreeBSD Jail.

Java 1.5, both the diablo binaries and the compile-from-source version.

Extremely easy:

freebsd$ portupgrade -Ns java/jdk15

Java 1.6 is a medium priority. Source code bases are starting to appear
that seem to be Java 1.6 specific, although I thought everything was
supposed to be backwards compatible, but apparently there is some
"breakage" in the SQL interfaces. I don't really have specifics.
