That pretty much covers everything. (If you wanted to do a special case for Solaris, it would be trivial.)

Seriously, JNI isn't a PITA for cross-platform, especially when just using arrays. The JNI API itself is the same across all platforms. To me, manually hacking Java byte codes sounds like much more of a PITA.
