Trinidad is overriding the "primitive" converters as well.
here is what our built-in faces-cfg does for Double:
<converter>
<converter-id>javax.faces.Double</converter-id>
<converter-class>org.apache.myfaces.trinidadinternal.convert.DoubleConverter</converter-class>
</converter>
and
<converter>
<converter-for-class>java.lang.Double</converter-for-class>
<converter-class>org.apache.myfaces.trinidadinternal.convert.DoubleConverter</converter-class>
</converter>
