Hi Guru, Kevin, Please review the webrev : http://cr.openjdk.java.net/~mcherkas/8149737/webrev/
Crash occurs during the page destroy and still there is are some pending sub-resource from network. I added a check for null, see line 814 in CachedResourceLoader.cpp to prevent crash.
JBS: https://bugs.openjdk.java.net/browse/JDK-8149737 Thanks, Mikhail.
