A lot of classes are trying to be loaded, but are not found.
This exception is just a consequence of that.
E.g. service org.netbeans.modules.debugger.jpda.projects.StepIntoActionProvider is trying to be loaded, but the appropriate module debugger.jpda.projects is not installed. That seems to be the root cause.
