Eclipse missing warning if variable used before assigned

We found a bug in old code which could be easily found if there would be a warning,

The issue was that inner class member was used but not assigned or initialized. Sample code minimized. Problem is that url is always null. 

 public class Main {
    public class Sender {
       private String url;

        public Sender() {
         }
         public void send() {
             OtherClass.send(url);
         }
      }
   }

In intellij it warns about variable never assigned. In eclipse I didn't find such warning.

The code is more complex and adding a warning at any level will reduce time to find similar bugs.

Is it possible in eclipse to warn in some way if variable is used before assigned/initialized ?

You can use SpotBugs(successor of findbugs) eclipse plugin. Right click on project Spotbugs->find bugs this will find these types of bugs.

I suggest also installing sonarlint plugin which has good static analysis capabilities.
