Not sure this is the reason, but your Java version is quite old. Instead of updating Java 6 you can also install Java 7.

I don't think this is due to Java version. Netbeans guys have a ​long history with this bug.

The issue was simply an EDT violation. And if we look at our code:

        ... (Splash screen operations)
        ...
        if (Main.pref.getBoolean("debug.edt-checker.enable", Version.getInstance().isLocalBuild())) {
            // Repaint manager is registered so late for a reason - there is lots of violation during startup process but they don't seem to break anything and are difficult to fix
            ...
        }

Well, it seems these violations DO break something here.
