Regression in getImplementationVersion from Jigsaw

[mandy chung]

Hi Michael,

It is indeed a bug and I file:
    https://bugs.openjdk.java.net/browse/JDK-8190987

The patch looks good and I will sponsor this patch for you.

Thanks for the regression test.  It'd be good to wrap the long lines and 
I will clean that up before I push.

thanks
Mandy
