   https://bugs.openjdk.java.net/browse/JDK-8073705


Open hotspot webrev:
http://cr.openjdk.java.net/~sspitsyn/webrevs/2015/hotspot/8073705-JVMTI-redefscale2.1/


Summary:

    This is the 2-nd round of performance/calability fixes in class 
redefinition.
    This time, the two remaining issues that were left alone in the 
first round fix:
      - optimized ConstantPoolCache::adjust_method_entries() is used for 
previous versions
      - the MemberNameTable::adjust_method_entries() has been optimized too
      - some cleanup


Testing:
   In progress: nsk redefine classes tests, JTREG java/lang/instrument, 
com/sun/jdi


Thanks,
Serguei
