Plus, I am using practically the same MANIFEST when building both in Netbeans and in Eclipse (in other words the dependencies would be the same whether I build with Netbeans vs. Eclipse), so why would the JAR built by Eclipse fail with this whereas the JAR built by Netbeans have no problem??

Thank you for that! I was wondering about that (whether a dependency would cause this problem). Do you have to check each class in the dependency JAR files (would be very painful!), or just in the JAR manifest?
