For me, I could reproduce the hang by doing this in a fresh-ish install:
1) Start Netbeans
2) Tools - Options - Fonts & Colors
3) With Profile at NetBeans and the Syntax tab selected, click on the ellipsis button to the right of the F_ont field.
4) Netbeans hangs.
I can confirm that commenting out AtkWrapper in /etc/java-7-openjdk/accessibility.properties fixed the hang.
