Hi devs, Please read this discussion at OpenJson issue tracker - https://github.com/tdunning/open-json/issues/11. It is related to https://issues.apache.org/jira/browse/WICKET-6329
In my opinion the current solution won't work in the long run. Maybe we should copy the classes from OpenJson instead of extending them. Having both OpenJson (dependency of Wicket) and the old JSON library in the classpath leads to inevitable problems like this one.
