RFR: 8160000: Runtime.version() cause startup regressions in 9+119

Hi, Claes.

Overall, this change looks good.  I just have a few concerns.

Have you built this forcing alternative build numbers?  I

Hi,

9+119 changed java.util.regex to initialize java.lang.invoke early, 
causing a number of easily reproducible startup regressions.

This patch uses the fact that we already maintain the version string 
constituents during build time to simplify creation of the 
java.lang.Runtime.version().

Webrev: http://cr.openjdk.java.net/~redestad/8160000/webrev.3/
Bug: https://bugs.openjdk.java.net/browse/JDK-8160000

Since getting Runtime.version() now does not have to touch 
java.util.regex classes we end up slightly ahead of previous builds for 
applications which does not use regular expressions.

Thanks!
