Patch GWT 1.5 / Hibernate4GWT

Pour utiliser Hibernate4GWT et GWT 1.5, il faut patcher Hibernate4GWT la partie "emul" sinon vous pouvez avoir ce genre de message à la compilation

[java] [ERROR] Line 22: The interface Comparable cannot be implemented more than once with different arguments: Comparable and Comparable 
[java] [ERROR] Line 86: Name clash: The method compareTo(Object) of type Date has the same erasure as compareTo(T) of type Comparable 
but does not override it 

En fait, l'émulation JRE de Date et Timestamp ne compile plus avec un JDK 1.5. Voici les patches à passer sur Hibernate4GWT 1.3 :
