Java compatability with IBM jdk

Hi there,
I was reading a couple of posts on your list in July 2001 and there was 
discussion about compatablility with java. I am interested in moving out
company webservers from windows to linux but have run into a lot of
problems with the old linuxthreads. Is there any java implimentation that
works with ngpt ? I notice that 
cut=
ldd /opt/java/jre/bin/exe/java
        libpthread.so.0 => /lib/i686/libpthread.so.0 (0x4002f000)
        libnsl.so.1 => /lib/libnsl.so.1 (0x40044000)
        libdl.so.2 => /lib/libdl.so.2 (0x4005a000)
        libc.so.6 => /lib/i686/libc.so.6 (0x4005e000)
        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
=cut

There was some mention of efforts to make your library binary compatable with 
linuxthreads. Is this the case yet ?

Thanks in advance
Bryan
