The headless test javax/swing/UIDefaults/6302464/bug6302464.java is failing on macOS12

As we do not currently have any macOS Apple Silicon systems configured to run *headless* tests so
I have to assume for now it is generic.

The test log says this

Note the test is HEADLESS and I am not sure what role that macOS font server error message plays in this.
