Spring 3 + Maven 3: SLF4J exception + versions?

[H Paul]

Jersey 2.0 + Spring 3 + Maven 3

Need some pointer on how to trouble shoot this issue? Could not see where those versions of SLF4J come from.
At server start up, I got this exception.

INFO: Spring WebApplicationInitializers detected on classpath: [org.glassfish.jersey.server.spring.SpringWebApplicationInitializer@c9f768]
SLF4J: The requested version 1.6.99 by your slf4j binding is not compatible with [1.5.5, 1.5.6, 1.5.7, 1.5.8, 1.5.9, 1.5.10, 1.5.11]
SLF4J: See http://www.slf4j.org/codes.html#version_mismatch for further details.

After scanning over several threads from stackoverflow, I tried several solutions but did not work for my case.
Finally, the one work best is load the versioned-issued-class to see where they came from.

For my case, I loaded those classes and found the classes came from some wrong jars that I do not expected. I fixed.

public class DebugWebApplicationInitializer implements WebApplicationInitializer {
	public void onStartup(ServletContext servletContext)
			throws ServletException {
        System.out.println("DebugWebApplicationInitializer");
        System.out.println(org.slf4j.Logger.class.getClassLoader().getResource("org/slf4j/Logger.class"));      
        System.out.println(org.apache.commons.logging.impl.SLF4JLocationAwareLog.class.getClassLoader().getResource("org/apache/commons/logging/impl/SLF4JLocationAwareLog.class"));        
        System.out.println(org.slf4j.Marker.class.getClassLoader().getResource("org/slf4j/Marker.class"));   
        System.out.println(org.slf4j.spi.LocationAwareLogger.class.getClassLoader().getResource("org/slf4j/spi/LocationAwareLogger.class"));        
	}
}

Worked and expected classes from below correct jars:
