[11u] java/awt/FontMetrics/MaxAdvanceIsMax.java test failure (was: [11u] RFR 8210782: Upgrade HarfBuzz to the latest 2.3.1)

[Lindenmaier, Goetz]

Hi Severin,

Thanks for looking at the issue!

I can reproduce the issue starting the test stand alone.
So it's not a problem of our test infrastructure.

But I can only reproduce it on a limited set of OSes:

linuxppc64le:
Red Hat Enterprise Linux Server release 7.2 (Maipo)
Red Hat Enterprise Linux Server release 7.3 (Maipo)
SUSE Linux Enterprise Server 15

I cannot reproduce it on these OSes:

linuxppc64le:
Red Hat Enterprise Linux Server VERSION 7.4 (Maipo)
SUSE Linux Enterprise Server 12 (ppc64le) VERSION = 12 PATCHLEVEL = 1
Ubuntu 16.04.3 LTS

Unfortunately, I don't have RHEL 7.2 or 7.3 on a linuxx86_64
box.  But the test is passing on SLES 15 on linuxx86_64.

I didn't yet open a bug for this, but the failure
is still there with jdk-11.0.4+2.

Checking 11.0.3, I see the failure too. So it is not
a regression. I also can reproduce it with jdk/jdk
on RHEL 7.2.
Our nightly tests of 11.0.3 and jdk/jdk are scheduled
on a SLES 12.3, therefor they don't show the problem.

I'll send you a jtr file of the failure off-list.

Best regards,
  Goetz.
