Ben> So its an optimisation (and therefore optional), right?
Yes. Though in practice it is probably necessary to get acceptable performance.
Without a verifier you must track the types of everything on the stack and in local variables (if you have a verifier you don't need to do this), and do assignability checks on arguments to all method calls, qualifying reference for a field lookup, etc.
This might be acceptable for a lightweight JVM, though, so we should rule it out.
Also, curious to know - what about out-of-band verifiers? So, for example, I verify something on my PC, sign it as verified, then run it on a Palm, with no verification?
Cheers,
ben.
