The native version works a lot better than the Linux version under
FreeBSD. Quite a few of the bigger Java projects will fail to run
correctly on the Linux version.

The build of the native jdk14 requires a boot-strap Java-compiler, the
one most readily available being the linux-sun-jdk14 version. Once the
Native JDK14 is installed the Linux one can be removed. Updates to the
native JDK can use the installed Native JDK as its boot-strap compiler.

You'll have to ask the OpenOffice maintainers about this one.
