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