Several people seem to have independently suggested the following (including
me), so here it is.

The attached patch (to the old, decrepit 1.3.100 actually) causes a
userland program (/bin/usrexec) to be invoked on unrecognised executable
files. (It's done within binfmt_script to avoid duplicate code, but you
could easily do it as a separate binfmt if you wanted too.)

/bin/usrexec is supposed to look for and invoke a userland interpreter to
execute the "executable".

Also attached is version 0.000001 of such an interpreter that can
recognise windows binaries (seems to work, but it's a hack) and java binaries
and invoke their respective interpreters. Clearly it can be improved.

With this patch, there is no need for all that BINFMT_JAVA stuff in
the kernel.

Cheers,
