6.The contents of the multibit-exe.jar will appear (.jar files are just plain zip archives), double-click on the line "org/multibit/model/bitcoin"
7. Double-click on the BitcoinModel.class - the contents of the file will appear, but you can't change it directly

I'm running OSX 10.9.5 with Multibit 0.5.18; when I open the /Applications/Multibit.app file in reJ I get a listing of folders: Contents, Contents/MacOS, Contents/Resources, Contents/Resources/Java, Contents/_CodeSignature

under Contents/Resources/Java I find multibit-exe.jar but double-clicking on it generates the error below:

Exception was thrown: Error parsing class file /Applications/Multibit.app: Invalid Magic: 50 4b 03 04

any thoughts?
