RFR: 8009615: JvmtiClassFileReconstituter does not create BootstrapMethod attributes

[Staffan Larsen]

JvmtiClassFileReconstituter does not create BootstrapMethod attributes when re-creating a class for retransformation. This fix uses the operands in the constant pool to re-create the BootstrapMethod attributes in the class file.

bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=8009615

Testing done: java/lang/instrument, com/sun/jdi, nsk.quick-jvmti.testlist

I have not written a regression test since this was found by running the existing java/lang/instrument/IsModifiableClassAgent.java test.

Thanks,
