A regression in Java 7 which freezes EDT of the application inside
after Gnome theme change.
The problem is reproducible with all of Java 7, 7u1, 7u2. Tested on Ubuntu 10.10 but most probably reproducible on all Gnome installations.
With Java 6u30 the problem is not manifested. The application correctly adapts its GTK L&F to the new theme.
