[7u-dev] Request for approval for 8011200 - Optimize empty ArrayList/HashMap

[Mike Duigou]

Hello all;

I would like to backport this change from Java 8. It has been baking in JDK8 preview builds for about two build cycles with no problems.

http://cr.openjdk.java.net/~mduigou/JDK-8011200/7u.0/webrev/

This is the same patch I submitted for review last week. The differences between the Java 8 and Java 7 versions of this patch are very minor. 

Thanks,

Mike
