1. Install the JRE test bundle JRE8u60b21 (download from http://jre.us.oracle.com/java/re/jdk/8u60/promoted/ea/b21/bundles)
2. Launch NVDA/JAWS (NVDA is 32bit(x86), so NVDA is for 32bit JRE/JDK; JAWS can be both x86 & x64 - its bitness must match with bitness of JRE/JDK)
3. Run SwingSet2 demo
4. Go to the "Look and Feel" Menu
5. Try to switch between the "Look and Feel" menu items

Expected Result:
NVDA screen reader or JAWS should read the "Look and Feel" Selections (Java, Nimbus, Motif, Windows) as you change or move your selections.

Actual behavior:
NVDA screen reader and JAWS can't read the "Look and Feel" Selections. And non-java app can read.
