Re: Problem with replacing the class

<replace-with> is related to "deferred binding", i.e. creating an instance through GWT.create(), where the actual class being instantiated is "bound" at compile-time, depending on properties (and/or permutations).

What you want to achieve can be done through "super sourcing". See "Overriding one package implementation with another" at

 I`m having troubles to replace one class by another

This is the class I want to replace:

package delightex.math.fp;

public class FloatBits {
public static int floatToRawIntBits(float v) { return Float.floatToIntBits(v); }
public static float intBitsToFloat(int v) { return Float.intBitsToFloat(v); }

So I have a better one in FloatBitsJs with the same API. 
And this I have in module.gwt.xml: 

<replace-with class="delightex.math.fp.FloatBitsJs">
<when-type-is class="delightex.math.fp.FloatBits"/>

But it does not get replaced. It still generates calls to FloatBits in both super-dev-mode and production modes. 
(Production is single permutation Chrome only "user.agent"="safari")

Any help ?
