Thai text can't be correctly rendered on Mac OS. Refer to the screenshot in attachment.

This does NOT happen when set logical font name "MonoSpaced", while Does when set the others or nothing by default.

Apple JDK 6 has the same behaviors.

(In the documentation at http://www.oracle.com/technetwork/java/javase/javase7locales-334809.html#jfc, Linux encodings and Peered AWT components are not supported in Thai writing system.)

Tested on Mac OS 10.9 + 8u5 b08 and 7u60 b10.
