[10] Review request: 8193823: gradle test fails to run when using jdk-10+36 as boot JDK

[Kevin Rushforth]

Phil,

Please review the following:

https://bugs.openjdk.java.net/browse/JDK-8193823
http://cr.openjdk.java.net/~kcr/8193823/webrev.00/

This will allow us to continue to build with the latest JDK and works 
around a gradle bug that was exposed with the time-based version string 
changes for JEP-322 that went into jdk-10+36.
