I recently ran into a problem where the 32bit JVM won't run on a 64bit host.
I, and at least one other person in -java thinks it has to do with 32 bit KSE

this still the issue? Could someone point me in the general direction of the
specifics of the problem (if they exist, if not, I may try to create a
simpler test case then java)?

I tried a few searches, but nothing matching what I remembered came up.

No, you can't run 32-bit libpthread on 64-bit kernel. There
are no compatiblity hooks in the kernel to handle 32-bit kse
interfaces. It is really too messy to provide it.


Daniel,

maybe you can send a followup to the following ?
http://www.freebsd.org/cgi/query-pr.cgi?pr=110655

Given that 32-bit libthr also doesn't work on 64-bit kernel, the only
option is to map thread libs to libc_r via libmap32.conf.
BTW, next time there is a poll about retiring libc_r please count me
against for precisely this reason.

I plan on making sure full 32-bit compat exists for both libthr and
libpthread and backporting it to 6.x for work. Very few things are
too hard to wrap with a 32-bit shim.
