However, frankly, I'd seriously recommend that you use a native OS
install to build the 64-bit JDK for either Windows or Linux. Even for
Solaris, where the 32/64 bit libraries and such are very well
segregated, there's lots to go wrong.
With the proliferation of LiveCD distros out there, if you don't want to
do an actual install to Hard Drive, you can still do a build when booted
