I'm trying to have a Java Timer in my EntryPoint:

Timer timer = new Timer();
timer.schedule(
   new TimerTask() {
       public void run() {
           //some code
       }
   }
   , 5000);

But when trying to compile this I got: No source code is available for type java.util.Timer; did you forget to inherit a required module?

What can I do to fix this error?

In GWT you are restricted to use all the Util package classes.

Here is the List of Classes only you can use from util class.

You can use GWT Timer class.

Example(from docs);

 public void onClick(ClickEvent event) {
    // Create a new timer that calls Window.alert().
    Timer t = new Timer() {   //import (com.google.gwt.user.client.Timer)
      @Override
      public void run() {
        Window.alert("Nifty, eh?");
      }
    };

    // Schedule the timer to run once in 5 seconds.
    t.schedule(5000);
  }
