Fix Request: Why? This bug can potentially crash an AArch64 JVM when a method has a suitably large enough i/vtable. What? The fix corrects an erroneous patch that without correction breaks the AArch64 build. Risk? The risk for the original patch was already low (see JDK-8195859). This correction doe snto add risk it merely removes breakage. Reviewers? It has been reviewed by Andrew Haley. webrev (for jdk10 and jdkdev) is here: http://cr.openjdk.java.net/~adinn/8196221/webrev/

The patch submitted in the review for 8195859 and committed to the repo was not the one applied to the JVM used to test the fix. It was an out of date version of the patch which contains a call with a missing argument and so breaks the Arch64 build.
