Tested jdk 8 b110:
lwawt takes a locks in the wrong order, but this particular issue can be fixed in the setFont(), because synchronisation on this is not necessary there.

Testcase attached:

Found one Java-level deadlock:
=============================
"AWT-EventQueue-0":
  waiting to lock monitor 0x00007fa355092108 (object 0x0000000700241b68, a LabelRepaint),
