This exception seems to be a consequence of some previous exception. I scanned the corresponding message.log and the initial exception seems to be:

java.lang.NullPointerException
	at sun.swing.SwingUtilities2.getLeftSideBearing
           (SwingUtilities2.java:274)
	at sun.swing.MenuItemLayoutHelper.getLeftExtraWidth

	at sun.swing.MenuItemLayoutHelper.calcExtraWidths

        ...

Event this exception doesn't seem to be related to GUI Builder or NetBeans. It is probably a JDK bug. In fact, it was already reported against JDK under no. 7037283, but it was closed as non-reproducible. Hence, if you are able to reproduce this exception reliably then, please, provide the details to JDK team. Thank you in advance.

The JDK issue: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7037283

I am closing this issue as INVALID because it seems to be outside NetBeans code.
