It appears the contrib javadoc settings were incorrect - thats why there was a bunch of errors about reading the package-list and why some contrib-to-core links wouldn't work

Same issue with the warnings from demo/core so changing those too - everything still appears to work, but contrib-core links that didn't now work and errors/warnings are gone
