Hi Christoph,

Ouch, I pasted the wrong bug ID before!! The patch I want to retire is
this (and sorry for the noise!):

While I still want to keep the others: 8224109, 8238942 and 8239091.

The FT_LOAD_NO_HINTING change is the problem for me. In some fonts and
with fractional metrics enabled it causes the rendering to be very
blurry. I do remember this to be the case in 8 or 7 at some point and
then it was finally fixed, so this change is a regression for me, this
is most likely tied to freetype but I don't understand why it's not
happening in 14+ with all the same code and compiled the same way, so
clearly I'm missing a patch somewhere and I would like to figure out
which one.

Yes, I think I'll take another day or two to test. I have built the
jdk with the default settings. I thought that the FREETYPE_PROPERTIES
thing was responsible at first but I didn't change this and is not set
in my build, but I'll need to do some more testing. I do remember we
had a couple of changes related to this as well as changes specific to
fractional metrics, but the code is actually the same at this stage
between 15-dev and 11-dev.
