A little while ago I was trying to troubleshoot some 2.8 issues and got annoyed about the fact that JSPWiki startup failures are effectively swallowed up by WikiException. Many of the Exception classes provide a constructor with a Throwable 'cause' parameter, which I thought would be a good thing here, too.
So, I have done that. Any objections to checking it in? Alternatively, I could check the changes into the (3.0) trunk. Andrew
