We have some Code Coverage results from JCov/JTreg!

[Martijn Verburg]

Hi Rory,

Thanks - we're looking into the existing Cloudbees Jenkins instance to do
this.  A second question quick question - do the numbers we're publishing
look right compared to your internal ones?  Appreciate non OpenJDK tests
run by Oracle means that they cover more.

Cheers,
Martijn
