> Pack200 bytecode offsets are not being calculated correctly when multi-instruction bytecodes
are present in the bytecode stream. This causes a problem for label bytecodes which follow
multi-instruction bytecodes.
> In short, if you have:
> <other bytecodes>
> aload0_*
> <other bytecodes>
> if*, goto*, or jsr*
> then the label of the if*, goto* or jsr* instruction will be off by the number of multi-instruction
bytecodes which come before it. This will usually result in an exception.
