---------------------------------------

Not sure about your question - I don't think we rely on maxLocals being the number of arguments in our code, but I'm not sure if that's quite what you meant...

> The value for max_locals is computed incorrectly for all methods which have long or double arguments (type J or type D). For instance, the max_locals for CpField's constructor:
> 	public CPField(CPUTF8 name, CPUTF8 descriptor, long flags, List attributes) {
> 		super(name, descriptor, flags, attributes);
> 	}
> is showing up as max_locals=5, when it should be max_locals=6 (1 for this, 1, for name, 1 for descriptor, 2 for flags, 1 for attributes).
