[8u20] Request for approval for bulk integration of hs25.20-b01

[Alejandro E Murillo]

Requesting approval to integrate hs25.20-b01 into jdk8u20-b01.

A webrev is available at:

http://cr.openjdk.java.net/~amurillo/8u20/hs25.20-b01-jdk8u20-b01.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.
