[7u4] Request for approval for bulk integration of hs23-b06 into jdk7u4

[John Coomes]

Requesting retroactive approval to integrate hs23-b06 into jdk7u4-b02
(jdk7u/jdk7u).

Despite my best intentions, I missed a key item on my checklist and
failed to request approval before pushing the changes to
jdk7u/jdk7u-dev and jdk7u/jdk7u.  Please advise as to the desired
course of action:  retroactive approval, rollback the offending
changesets, or some other alternative.  Details on the integration are
below.

A webrev (XXL) is available at:

	http://cr.openjdk.java.net/~jcoomes/7u/hs23-b06-jdk7u4-b02/

Pre-integration testing (PIT) was run by SQE, who analyzed the results
and have given their approval for integration.

The list of fixes in the integration is below.  All have undergone
nightly testing and are already in the jdk8 master repository.
