* javax/swing/text/JTextComponent.java (JTextComponent): Added repaintListener which issues repaint requests when the underlying document changes. (setDocument): Adds repaintListener to document when the document is changed. * javax/swing/text/DefaultEditorKit.java: Removed repaint calls on JTextComponent. This is now handled through a DocumentListener in JTextComponent that repaints the component when needed. From-SVN: r98403
