While assisting with the investigation of:
[JDK-8160664] JVM crashed with font manager on Solaris 12
https://bugs.openjdk.java.net/browse/JDK-8160664
we discovered that if none of the font directories are present on the system
FcFontList() returns NULL, but if at least one is present, even if empty,
then it returns a valid pointer to a list of 0 entries.
This doesn't seem to be documented anywhere that I can find, but you
can see the fc-list utility checks for it all the way back to the
first revision in git. Is this intentional? Should it be documented
so other application authors know to check for NULL?
