The fix seems fine but if the app isn't setting null how are we getting
null here ?
Frequent hierarchy validation does not in itself explain that to me.

Hello.
Please review the fix for JDK 14.
Bug: https://bugs.openjdk.java.net/browse/JDK-8233657
Fix: http://cr.openjdk.java.net/~serb/8233657/webrev.00
During testsprint I have analyzed some intermittent failures of our
tests and
found some intermittent NPE. The root cause is the calling of
Component.validate()
if the null font is used. The bug reproduced mostly on HiDPI systems
where we
validate the hierarchy of components more often.
The validate method is aupdated to use the same logic as setFont(),
where null value
is ignored and never passed to the peer.
Actually the fix is simpler than the tests problem listing due to
product bug.
