Classic VM (build JDK-1.2.2-W, native threads, symcjit)

============ Description:
The javax.swing.text.DefaultHighlighter.addHighlighter() correctly accepts any
painter that implements the Highlighter.HighlightPainter interface and will
create a HighlightInfo object for it, but
javax.swing.text.DefaultHighlighter.removeAllHighlights() throws a
ClassCastException if any of the HighlightInfo objects aren't of class
javax.swing.text.DefaultHighlighter.LayeredHighlightInfo. The removeHighlight()
method correctly handles HighlightInfo objects.

============ Source code:
Source code to reproduce the problem isn't necessary, since the problem is
obvious just by looking at the addHighlight() and removeAllHighlights() code in
jdk1.2.2\src\share\classes\javax\swing\text\DefaultHighlighter.java

============ Error message and trace:
Exception occurred during event dispatching:
java.lang.ClassCastException: javax.swing.text.DefaultHighlighter$HighlightInfo
