LeakCanary doesn't catch leaks that I have deliberately added. What am I missing?

We've integrated LeakCanary to help us resolve what we believe are memory leak issues. In order to make sure we have every thing set up right I've created a static reference that will not be removed and told leakCanary to watch it, 

public class Cat {
 }

 public class Box {
        public Cat hiddenCat;
 }

public class Docker {
     public static Box container;
}

In the MainActivity

    Box box;
    Cat schrod;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    box = new Box();
    schrod = new Cat();
    box.hiddenCat = schrod;
    Docker.container = box;
    Application.getRefWatcher().watch(schrod);


    System.gc();
}

in the Application class

    private static RefWatcher sRefWatcher;

    @Override
    public void onCreate() {
        sRefWatcher = LeakCanary.install(this);  
    }       
    public static RefWatcher getRefWatcher() {
        return sRefWatcher;
    }

and in the build.gradle file:

 dependencies {
        debugCompile 'com.squareup.leakcanary:leakcanary-android:1.3.1'
        releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.3.1'
 }

What am I missing that it never informs me that the reference to the schrod object sticks around?

You might need to update the build.gradle dependencies to latest version (found on the Getting Started guide on this page: https://github.com/square/leakcanary) which happen to be:

debugCompile 'com.squareup.leakcanary:leakcanary-android:1.4-beta2'
releaseCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2'
testCompile 'com.squareup.leakcanary:leakcanary-android-no-op:1.4-beta2'
