Error description
Error Message: Methods java/lang/invoke/MethodHandles$Lookup.unreflect(), java/lang/invoke/MethodHandles$Lookup.findSpecial() and java/lang/invoke/MethodHandles$Lookup.findVirtual() return an overly restricted MethodHandle when the protected (non-static) method is defined in a different runtime package from the accessing class, and the accessing class is NOT a subclass of the defining class. . Stack Trace: N/A .
Local fix
Problem summary
In the scenario described above, the receiver argument that was being returned in the MethodHandle, was being incorrectly narrowed down to the accessing class.
Problem conclusion
The JVM has been changed such that, in the above condition, the receiver argument that is returned in the MethodHandle will be narrowed down to the accessing class, only when the accessing class is a subclass of the class where the protected method is defined. . This APAR will be fixed in the following Java Releases: 8 SR2 (8.0.2.0) 7 R1 SR3 FP40 (7.1.3.40) . Contact your IBM Product's Service Team for these Service Refreshes and Fix Packs.
