[Bug swing/27834] New: Second and subsequent .setText calls fail on JTextPane with html content type

[audriusa at bluewin dot ch]

The first attempt to display the simple html document (plain text only, no
formatting) succeeds and the second and subsequent attempts fail with the
following exception:

I mark this as Swing because the exception is thrown from the swing classes,
not from the HTML parser or text.html. However if the content type is set to
the text/plain, the repetetive calls succeed.

The test case (hope will be a html demo in the future) is attached.
