Requesting approval to integrate hs25.60-b12 into jdk8u60-b12.

A webrev is available at:

http://cr.openjdk.java.net/~amurillo/8u60/hs25.60-b12-jdk8u60-b12.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 jdk9 repository.
