based on patch contributed by Andy Clement
Generalizes the patch with a method org.aspectj.weaver.bcel.Utility.copyInstruction
that works-around the bug in Select.copy(). Changed all calls to
Instruction.copy() to use this new method, would be nice to add the
rule:
* declare error:
* call(* Instruction.copy()) && within(org.aspectj.weaver)
* && !withincode(* Utility.copyInstruction(Instruction)):
* "use Utility.copyInstruction to work-around bug in Select.copy()";
