Annotating method parameters with @Inject results in ClassCastException #112

When putting the @Inject annotation to a method parameter a ClassCastException is thrown in InjectProcessor#getInjectedClasses():

java.lang.ClassCastException:$MethodSymbol cannot be cast to javax.lang.model.element.TypeElement
at dagger.internal.codegen.InjectProcessor.getInjectedClasses(
at dagger.internal.codegen.InjectProcessor.process(

That exception hides the error which would be thrown by the compiler due to the annotation being given at an unsupported element type ("annotation type not applicable to this kind of declaration").
