JCov and coverage numbers on OpenJDK

[Mani Sarkar]

Hi Ben,

The JCov coverage report for both OpenJDK8 and OpenJDK9 are linked from two
places at the least:

Recent article in Voxxed:
https://www.voxxed.com/blog/2015/04/putting-java-tools-and-libraries-to-use-on-openjdk9/
(look for first hyperlink)
Our community driven gitbook i.e. Adopt OpenJDK Getting Started Kit
<http://neomatrix369.gitbooks.io/adoptopenjdk-getting-started-kit/>, see
http://neomatrix369.gitbooks.io/adoptopenjdk-getting-started-kit/content/advanced-steps/openjdk_code_coverage.html
(first two hyperlinks on the page)

On the CloudBees Jenkin server we don't have a direct link but can download
the reports as zipped files, see
https://adopt-openjdk.ci.cloudbees.com/view/OpenJDK/job/openjdk-1.8-linux-x86_64/lastSuccessfulBuild/artifact/
https://adopt-openjdk.ci.cloudbees.com/view/OpenJDK/job/openjdk-1.9-linux-x86_64/lastSuccessfulBuild/artifact/

Hope this helps for your InfoQ article, if you need to know anything John
Oliver, and Martijn are also great sources to inquire with, with regards to
JCov and the work that has been done in this respect.

Cheers,
Mani
