JDK-7001379 - bootstrap method data needs to be moved from constant pool to a classfile attribute

Sub Tasks

Description
When bootstrap_method_ref in BootstrapMethods attribute points to a wrong CP entry (non-MethodHandle), JVM throws ClassFormatError with a message, where method index and class file name is garbage:

Exception in thread "main" java.lang.ClassFormatError: bootstrap_method_index 141157536 has bad constant type in class file ??

It seems like the corresponding sprintf() does not receive method index and class file name.

This bug was introduced by CR 7001379.

Comments
EVALUATION

Two check_property calls without specifying the index were added with 7001379.

SUGGESTED FIX

Simply add the index as argument to check_property.
