Bootstrap arguments

[Jeroen Frijters]

Hi all,

I was surprised by this as well (from an implementers point of view), because the use of asType is an implementation detail. Normally when you call a method taking a boolean/byte/short/char you also load an int onto the stack, so why would this case be any different?

Not that it makes a great deal of difference, of course.

Regards,
Jeroen
