Requesting approval to integrate hs23-b08 into jdk7u4-b05.
A webrev is available at: http://cr.openjdk.java.net/~amurillo/7u4/hs23-b08-jdk7u4-b05.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.
