Below is a swing applet that demonstrates problem -- on my machine.
I set the highlighter for the textpane to null expecting no highlighting
to occur when I click on text in the textpane.

But clicking on a word in the text pane partially highlights the word -- on my
machine. This error is also seen on JDk1.4beta3.

Your documentation says:

setHighlighter public void setHighlighter(Highlighter h) Sets the highlighter to
be used. By default this will be set by the UI that gets installed. This can be
changed to a custom highlighter if desired. The highlighter can be set to null
to disable it. A PropertyChange event ("highlighter") is fired when a new
highlighter is installed.
