Hi,

You are absolutely right! Running in the software pipline yields the
correct results on java8 as well. In general although the fonts produced
by the SW-pipeline look different to the ones from the es2 one (they
look thinner).

I'll dig further - this is a blocking issue for one of our applications
as it makes the whole UI look slugish and none professional and moving
to Java9 is currently out-of-scope.
