[jdom-interest] UnsupportedClassVersionError when running with
jhunter at servlets.com

The official distribution was, and is, built against JDK 1.2 to avoid
this issue. If you're getting that error it means you're not using the
JAR we officially distribute. Why don't you download again and check?
If you still get the error, you may have a second copy of the JAR
somewhere like in your std extension directory that you're unaware of.
