text/rtf -> text/html: Strikethrough formatting not being converted

[Robert-Rendell]

Given the following code:

public class RTF2HTMLConverterJEditorPane implements RTF2HTMLConverter {
	public static final RTF2HTMLConverter INSTANCE = new RTF2HTMLConverterJEditorPane();
	
	private RTF2HTMLConverterJEditorPane() {}

	@NotNull
	public String rtf2html(@NotNull final String rtf) {
		final JEditorPane p = new JEditorPane();
		p.setContentType("text/rtf");
		final EditorKit kitRtf = p.getEditorKitForContentType("text/rtf");
		try {
			kitRtf.read(new StringReader(rtf), p.getDocument(), 0);
			final Writer writer = new StringWriter();
			final EditorKit editorKitForContentType = p.getEditorKitForContentType("text/html");
			editorKitForContentType.write(writer, p.getDocument(), 0, p.getDocument().getLength());
			return writer.toString();
		} catch (IOException | BadLocationException e) {
			throw new RTF2HTMLException("Could not convert RTF to HTML.", e);
		}
	}
}

The following RTF string:

\strike - strikethrough\strike

I don't see strikethrough formatting being converted to HTML.
