JFreeChart: XYLineAndShapeRenderer with error bars

Attached is some code (SSCCE, except you need jfreechart jars), borrowed and then modified from the JFreeChart site. I want to display error bars along with the data but can't get them to show.
What do I need to do?

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The first problem, at least, is a bug in an optimisation introduced in JFreeChart 1.0.6, where the renderer tries to process only the items that are visible in the chart (which can save a lot of processing if the data items are ordered by x-value).

The problem is that the drawSeriesLineAsPath option assumes that the renderer will be passed the 0 and N-1 items. With the optimisation, that doesn't actually happen when the plot is zoomed in. The quick fix is to call state.setProcessVisibleItemsOnly(false) in the renderer's initialise() method. I'll try to find a fix that will retain the optimisation.
