jetty exception and failed startup

I upgrade gwt version from 2.3 to 2.7 and some other modules. maven build end successfully, but when I run in superDevMode get an exception

java.lang.IllegalArgumentException: Object of class 'com.google.gwt.dev.shell.jetty.JettyLauncher.WebAppContextWithReload' is not of type 'org.eclipse.jetty.webapp.WebAppContext'. Object Class and type Class are from different loaders.

I haven't any idea.

Using:

[WARN] Failed startup of context c.g.g.d.s.j.WebAppContextWithReload{/,file:/home/.../modules/core-war/target/x12/},/home/.../modules/core-war/target/x12
java.lang.IllegalArgumentException: Object of class 'com.google.gwt.dev.shell.jetty.JettyLauncher.WebAppContextWithReload' is not of type 'org.eclipse.jetty.webapp.WebAppContext'. Object Class and type Class are from different loaders.

I removed gwt-dev.jar from my WEB-INF/lib and add a dependency to this jar file by add a path inside classpath of my ant

        <java classname="com.google.gwt.dev.DevMode" dir="core-war/target/" failonerror="false" fork="true">
        <classpath>
            <path refid="project.source.path"/>
            <path refid="project.class.path"/>
            <path location="${basedir}/build-conf/lib/ojdbc-11g-1.6.jar" />
            <path location="${mvn.repo.dir}org/netezza/nzjdbc/4.6/nzjdbc-4.6.jar" />
            <path location="${mvn.repo.dir}/com/google/gwt/gwt-dev/${gwt.version}/gwt-dev-2.7.0.jar" />
        </classpath>

The gwt-dev.jar is on the web server classpath and it should not be. Remove the gwt-dev.jar. If it's maven, provide the scope as <scope>provided</scope> and it will not get put into the WEB-INF/libs folder. Check the WEB-INF/libs folder for gwt-dev.jar and remove it if need be.
