I would like to request for a review of changes whose details are as 
follows:

Bug fixed: https://jbs.oracle.com/bugs/browse/JDK-8009552
Webrev: http://cr.openjdk.java.net/~bharadwaj/8009552/webrev/

Summary of changes :
To support JDK 8 features, javac now generates invokespecial 
instructions to reference interface methods. The proposed change 
modifies bytecode verification (in old verifier) of Java 8 classfiles to 
allow invokespecial to refer to methods in CONSTANT_InterfaceMethodref 
as well as in CONSTANT_Methodref. Consequently, class hierarchy walk to 
validate the operand of invokespecial is restricted to classes with 
version less than 52.

Note that this change is to the old verifier. The new verifier (split 
verifier) already handles this.

Thanks,

Bharadwaj
