[7u6] Request for Approval : 6924259: Remove String.count/String.offset

[Mike Duigou]

Hi,

This is a request to include an enhancement into JDK 7u6:
 6924259: Remove String.count/String.offset

Vladimir Kozlov has committed the required HotSpot changes already (http://hg.openjdk.java.net/jdk8/jdk8/hotspot/rev/8f972594effc). The changes were imported into the jdk7u-dev workspace as part of Alejandro's bulk push. <http://mail.openjdk.java.net/pipermail/jdk7u-dev/2012-May/003155.html>

This change has been reviewed on corelibs-dev and has also had considerable internal review as it changed hands during development. The latest webrev for this change is at:
 http://cr.openjdk.java.net/~mduigou/6924259/1/webrev/

I hope to push in time for the b13 build to:
 ssh://hg.openjdk.java.net/jdk7u/jdk7u-dev-gate/jdk

Thanks!

Mike
