Erik:
This patch adds comparison of the test image, if present in both build output directories. I also cleaned away comparing of some old Oracle closed images that no longer exist.Bug: https://bugs.openjdk.java.net/browse/JDK-8220530 <https://bugs.openjdk.java.net/browse/JDK-8220530?filter=-1> Webrev: http://cr.openjdk.java.net/~erikj/8220530/webrev.01/index.html
Looks good to me. Tim
