I looked at the source and realised this feature wasn't fully
implemented... it should work in pre5. If it doesn't, please remind me
to take another look.

If you have access to the source code, can you try changing the
updateRenderingHints() method in org/gjt/sp/jedit/TextAreaPainter.java
to this:

	private void updateRenderingHints()
	{
		HashMap hints = new HashMap();

		if(antiAlias)
		{
			hints.put(RenderingHints.KEY_RENDERING, RenderingHints.VALUE_RENDER_QUALITY);
			hints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
			hints.put(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
		}
		else
		{
			hints.put(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_OFF);
			hints.put(RenderingHints.KEY_TEXT_ANTIALIASING, RenderingHints.VALUE_TEXT_ANTIALIAS_OFF);
		}

		hints.put(RenderingHints.KEY_FRACTIONALMETRICS,
			fracFontMetrics ?
				RenderingHints.VALUE_FRACTIONALMETRICS_ON
				: RenderingHints.VALUE_FRACTIONALMETRICS_OFF);

		renderingHints = new RenderingHints(hints);
		fontRenderContext = new FontRenderContext(null,antiAlias,
			fracFontMetrics);
	}

It differs from the original in that when anti-aliasing is disabled, it
sets both the ANTIALIASING and TEXT_ANTIALIASING hints to OFF, where
previously it only changed the ANTIALISING hint.

This is a known bug -- I will try to fix it in a future release.
