32-bit JVMs have somewhat limited memory (somewhere around 2GB depending
on the platform). 64-bit JVMs can support a /lot/ more. You don't
necessarily have to trade-off between threads and heap.

Actually, I have no idea how to allow more threads in a JVM. I would
imagine that they are simply limited my the amount of (Java heap as well
as JVM) memory you have available and the process thread limit set in
your OS.

I suppose if the only way to support 8192 threads is to run two
4096-thread processes at once, that's what you gotta do.
