[7u4] Request for approval for bulk integration of hs23-b18

[Alejandro E Murillo]

Requesting approval to integrate hs23-b18 into jdk7u4-b17.

A webrev is available at:

http://cr.openjdk.java.net/~amurillo/7u4/hs23-b18-jdk7u4-b17.webrev/

Pre-integration testing is in progress; the integration will proceed
only after SQE has analyzed the results and approved.

The fixes in the proposed integration are below.  All have undergone
nightly testing and are already in a jdk8 repository.
