> There is a subset of the general problem that we should be able to solve by looking at invokedynamic/invokehandle call sites and MethodHandle constant pool entries. If a replay references a hidden class that is discoverable in one of those locations, then we can use the location as a replacement for the transient VM name.
>
> Examples of references to hidden class locations:
>
> @bci compiler/ciReplay/CiReplayBase$TestMain test (I)V 1 <appendix> argL0 ;
> @bci compiler/ciReplay/CiReplayBase$TestMain main ([Ljava/lang/String;)V 0 <appendix> form vmentry <vmtarget> ;
> @cpi compiler/ciReplay/CiReplayBase$TestMain 56 form vmentry <vmtarget> ;
