RFC: 8223915: JVMTI Spec: can_redefine_any_class capability spec is inconsistent

[serguei . spitsyn]

Please, review CSR:
  https://bugs.openjdk.java.net/browse/JDK-8223915
for enhancement:
  https://bugs.openjdk.java.net/browse/JDK-8046018

Summary:

 The spec of the "can_redefine_any_class" needs to be more clear and 
consistent.
 The suggestion is to change the "can_redefine_any_class" capability spec|
  from:||
    "Can modify (retransform or redefine) any modifiable class. See 
IsModifiableClass." |||

|to: "Can redefine any modifiable class. See IsModifiableClass. 
(can_redefine_classes must also be set)" |The RetransformClasses can cause class redefinitions.
But I'm not sure, it is worth to me mentioned, as it is confusing.

Thanks,
