Question

I have one user who gets an error message when he closes his browser. This only happens when he has visited a page which contains my applet. It seems to have been registered as a bug at Sun but that was many years ago. He is using Java 1.6 and IE7.

Has anyone seen this before and know a solution or work-around?

java.lang.NullPointerException: null pData     at sun.awt.windows.WComponentPeer.hide(Native Method)     at java.awt.Component.removeNotify(Unknown Source)     at java.awt.Container.removeNotify(Unknown Source)     at java.awt.Container.removeNotify(Unknown Source)     at java.awt.Container.removeAll(Unknown Source)     at sun.plugin.viewer.frame.IExplorerEmbeddedFrame.windowClosed(Unknown Source)     at java.awt.Window.processWindowEvent(Unknown Source)     at java.awt.Window.processEvent(Unknown Source)     at java.awt.Component.dispatchEventImpl(Unknown Source)     at java.awt.Container.dispatchEventImpl(Unknown Source)     at java.awt.Window.dispatchEventImpl(Unknown Source)     at java.awt.Component.dispatchEvent(Unknown Source)     at java.awt.EventQueue.dispatchEvent(Unknown Source)     at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source)     at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source)     at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)     at java.awt.EventDispatchThread.pumpEvents(Unknown Source)     at java.awt.EventDispatchThread.pumpEvents(Unknown Source)     at java.awt.EventDispatchThread.run(Unknown Source) 

UPDATE The user removed Google Desktop and the problem has not occured since. So there you go… Thanks everyone!

Answer 1

I used to get that error a lot for just about every applet that was loaded in the browser. I never figured out how, but Google Desktop was breaking java in some way. After uninstalling google desktop the error went away.
