JTextPaneで検索結果のハイライト表示と文字色変更を同時に行う

StyledDocument doc = textPane.getStyledDocument();
Style def = doc.getStyle(StyleContext.DEFAULT_STYLE);
Style htf = doc.addStyle("highlight-text-foreground", def);
StyleConstants.setForeground(htf, new Color(0xFF_DD_FF));
// ...

//clear the previous highlight:
Highlighter highlighter = textPane.getHighlighter();
for (Highlighter.Highlight h: highlighter.getHighlights()) {
  doc.setCharacterAttributes(
      h.getStartOffset(), h.getEndOffset() - h.getStartOffset(), def, true);
}
highlighter.removeAllHighlights();
// ...

//match highlighting:
Highlighter.Highlight hh = highlighter.getHighlights()[current];
highlighter.removeHighlight(hh);
highlighter.addHighlight(
    hh.getStartOffset(), hh.getEndOffset(), currentPainter);
doc.setCharacterAttributes(
    hh.getStartOffset(), hh.getEndOffset() - hh.getStartOffset(), s, true);
scrollToCenter(textPane, hh.getStartOffset());
