There's another function in jvmtiRedefineClasses that can also be removed. We used to find nmethods dependent on a redefined klass by walking the code cache for each klass. Now there's a code cache walk at the end. There's a comment before the function that should be rewritten, so I've assigned this to myself and it's technically jvmti. Thanks [~kvn]
