My favourite JVM trivia, although I openly admit I don't know if it's still true, is the fact that the size of a boolean is not defined.

If you ask a typical grad the size of a bool they will inevitably say one bit, but, CPUs and RAM, etc don't work like that, typically they expect WORD sized chunks of memory - meaning that the boolean size of one but becomes a WORD sized chunk, assuming that it hasn't been packed
