Description arittner 2005-01-14 11:26:42 UTC 
To reproduce the bug:

Open Javadoc Index Search (e.g. for 1.4.2)
Find the word "help"
You get helpButtonMnemonic
        helpButtonText
        helpButtonToolTipText

Click "fast" between helpButtonMnemonic and
helpButtonText.

Yout get this exception:

java.lang.NullPointerException

Comment 1 Jan Pokorsky 2005-02-08 18:14:52 UTC 
Yes, I can reproduce it smoothly too [winXP, jdk 1.5.0-b64] and it is
pretty annoying.

The javadoc module can hardly fix this since it delegates showing of
url to the HtmlBrowser.setURL that is a part of openide.

NPE occurs because the document is missing
Document.StreamDescriptionProperty (should be URL). So I would suggest
to investigate why the SwingBrowserImpl is resetting that property to
null.
