I started to update a wep application from Tomcat 6 to the current version of Tomcat (7-27). The problem arises when I start-up the server with the following error message:

Some dependencies have the scope "provided" and are not included in the war (as long tomcat doesn't use them)!

When I debug the code in org.gatein.pc.portlet.impl.jsr168.ClassInstanceLifeCycle.create(...) it stops on the second line
Class clazz = classLoader.loadClass(className);
if (expectedClass.isAssignableFrom(clazz)) {
Class<? extends T> castedClass = clazz.asSubclass(expectedClass);
Constructor<? extends T> ctor = castedClass.getConstructor();
instance = ctor.newInstance();
}
else {
String msg = "Cannot create " + type + " with class " + className + " because it does not implement the expected interface " + expectedClass.getName();
throw new PortletInitializationException(msg);
}
My suggestion was first that there is a problem with the class loader but it shouldn't be, because the first line correctly loads the class PortletSecurityFilter. The expected class is javax.portlet.filter.PortletFilter as expected. Why the class is not assignable from?
I thank for any help!
