[7u6] Request for Approval : 7173432: Remove String.count/String.offset

[Mike Duigou]

Hi,

This is a request to include a bug fix into JDK 7u6:
6924259: Handle insertion of null key at HashMap resize

This is a bug fix for the recently integrated CR#7126277 which fixes a bug uncovered during integration testing.

There is a webrev of the fix plus a regression test open for review. I still need a reviewer in addition to approval before I can commit.

http://cr.openjdk.java.net/~mduigou/7173422/0/webrev/

This fix blocks the b13 build. When ready I will push to:
ssh://hg.openjdk.java.net/jdk7u/jdk7u-dev-gate/jdk

Thanks!

Mike
