Is there a cache? I was under the impression that J3 isn't a just in
time compiler. Doesn't the J3 simply essentially substitute machine
code for bytecodes on a per-bytecode basis as it goes? The plugin
looks to see if a bytecode is in its case statement, and if it is it
executes machine code for it. If a bytecode is not in the case
statement it feeds back into the regular bytecode interpreter.
Anyone care to clarify? :-)
