The fix for the following bug:

    7064927 4/4 retransformClasses() does not pass in LocalVariableTable
                of a method

was integrated in JDK8-B19/HSX-23-B09 in the hotspot repo:

http://hg.openjdk.java.net/hsx/hotspot-rt/hotspot/rev/c01e115b095e


The tests for java.lang.instrument live in the jdk repo.
This bug is being used to integrate the following test:

    java/lang/instrument/VerifyLocalVariableTableOnRetransformTest.sh
Here is what a passing run with JDK8-B51 looks like:
