JDK 1.6.0_01

ADDITIONAL OS VERSION INFORMATION :

A DESCRIPTION OF THE PROBLEM :
RTFEditorKit does not parse superscript (keyword super) or subscript (keyword sub). There is a TODO on this in the JDK 5.0 source code (RTFReader line 1214).

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Open up Microsoft Word, put in some superscripts and subscripts, output to rtf. Read in using RTFEditorKit. Thrill at the element containing your super/subscripts -- yet is not super/subscripted.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Separate element with super/subscript attribute.
ACTUAL -
No super/subscript attribute present.

REPRODUCIBILITY :
This bug can be reproduced always.
