I'm far from certain that it matters to a compiled bytecode object whether the JVM its running on is 32 or 64 bit. It shouldn't matter, since that would drive a coach & horses through the WORA concept. > I would imagine this is something that has rarely if ever been tried > because normally it would make sense to use the Linux Java. > Bytecode shouldn't care about either OS or the address size the JVM is implemented in.
