      Description

      ADDITIONAL SYSTEM INFORMATION :
      java version "1.8.0_172"
      Java(TM) SE Runtime Environment (build 1.8.0_172-b11)
      Java HotSpot(TM) 64-Bit Server VM (build 25.172-b11, mixed mode)


      A DESCRIPTION OF THE PROBLEM :
      JTextPane with RTFEditorKit displays background color for specific word(changed by the doc.setCharacterAttributes()), writes it into rtf file, but doesn't read it.

      The bug in the RTFEditor$AttributeTrackingDestination.handleKeyword(String keyword, int parameter) method: it stores "cf" keyword into "parserState", but doesn't store "cb" keyword. Just need to add :
              if (keyword.equals("cb")) {
                  parserState.put(keyword, Integer.valueOf(parameter));
                  return true;
              }


      REGRESSION : Last worked in version 8u202

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      1. Create JTextPane with RTFEditorKit
      2. Set YELLOW color as background color for some word
      3. Save RTF into file
      4. Read RTF from file and display it

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Background color of word should be YELLOW
      ACTUAL -
      Background color of word is WHITE
