[Yangfei (Felix)]

Hi,

Original Bug: https://bugs.openjdk.java.net/browse/JDK-8203699 
Original patch: http://hg.openjdk.java.net/jdk/jdk/rev/cc2b36619704 

This bug can be reproduced with 8u aarch64 fastdebug build by running this test: 
    http://cr.openjdk.java.net/~fyang/8203699-8u/TestDefenderMethodLookup.java 

$./jtreg/bin/jtreg -othervm hotspot/test/TestDefenderMethodLookup.java

Webrev for 8u-aarch64: http://cr.openjdk.java.net/~fyang/8203699-8u/webrev.00/ 

Performed full jtreg test with 8u aarch64 fastdebug & release build.  OK to backport?

Thanks,
Felix
