Oh yes, It happens after I added these dependencies :

>         <!--AspectJ-->
>         <dependency>
>             <groupId>org.aspectj</groupId>
>             <artifactId>aspectjrt</artifactId>
>             <version>1.6.11</version>
>         </dependency>
> 
>         <!--youtube-->
>         <dependency>
>             <groupId>com.google.apis</groupId>
>             <artifactId>google-api-services-youtube</artifactId>
>             <version>v3-rev144-1.20.0</version>

>         </dependency> 

>    <dependency>
>        <groupId>com.sun.jersey.contribs</groupId>
>        <artifactId>jersey-multipart</artifactId>
>        <version>1.9.1</version> 
>    </dependency>

And the problem is resolved when I delete these dependencies :)

I will search which of these dependencies uses SLF4J and I ll make an exclude ...

Thanks
