RFR: 8193660 Check SOURCE line in "release" file for closedjdk

[Randy Crihfield]

I need to revise the resource file test created for JDK-8192837
The new bug is https://bugs.openjdk.java.net/browse/JDK-8193660

The webrev is located at 
http://cr.openjdk.java.net/~shurailine/8193660/webrev.00/ 
<http://cr.openjdk.java.net/%7Eshurailine/8193660/webrev.00/>

Any comments/suggestions are welcome, also I will need a sponsor for it 
at the end…
