Java: Error creating bean with name 'loadTimeWeaver'?

I am currently working on a maven project but every time i try to deploy my war i get the exception below:

ERROR [DispatcherPortlet:276] Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.weaving.AspectJWeavingEnabler#0': Initialization of bean failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'loadTimeWeaver': Initialization of bean failed;  nested exception is java.lang.IllegalStateException: ClassLoader [org.apache.catalina.loader.WebappClassLoader] does NOT provide an 'addTransformer(ClassFileTransforme r)' method.

I simply don't understand when i have everything in place properly why this error. Please checkout my declaration in POM.xml

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.4</version>
    <configuration>
            <forkMode>once</forkMode>
            <argLine>
                 -javaagent:"path\spring-instrument-3.1.0.RELEASE.jar"
            </argLine>
            <useSystemClassloader>true</useSystemClassloader>
    </configuration>
</plugin>

Please guide.
