Nosysinfo disables the NPTL threads in the newer kernels, which Java
versions below 1.4.2 are incompatible with. 
I found out about it via another list where users were reporting
problems with java on these platforms.

You can also do export LD_ASSUME_KERNEL=2.4.1 (uses the original linux
threads with floating stacks)
Or LD_ASSUME_KERNEL=2.2.5 (uses linux threads without floating stacks)

I believe this is only applicable to the RedHat kernel in RH9 and Fedora
core 1. If you build your own 2.4 kernels, they don't have NPTL threads,
so there is no issue. 2.6 seems to implement them in such a way as to
not break java. 

If you do a search for nosysinfo and LD_ASSUME_KERNEL you can find
hundreds of other users that have issues with java as well :)
