RFR: 8342105: JVM Crash when Jacoco and JFR are active [v2]

[Markus Grönlund]

> Greetings,
> 
> JFR hooking invocations of deprecated methods have a problem supporting Condy because these involve indirect invocations (via a bootstrap method) and do not have a reified bytecode invocation instruction (which gets support structures in the MDO).
> 
> The bytecode for a condy invocation is ldc or fast_aload (when the bytecode is rewritten), and no MDO support structures are added for these.
> 
> ConstantPool idx 0x55: ("Condy")
> 
> 55 = Dynamic 0:54 // 0:$jacocoData:Ljava/lang/Object;
> 
> CONSTANT_Dynamic_info {
>       u1 tag;
>       u2 bootstrap_method_attr_index; [0]
>       u2 name_and_type_index; [54]
> }
> 
> For additional details, please take a look at the JIRA issue. 
> 
> Testing: jdk_jfr
> 
> Thanks
