MyClass is not a generic type; only generic types can be parameterized

[dinosaurus]

Hello,

I have the following class which has not methods at all:

public class MyClass extends LinkedList<MyAnotherClass> {

}


In GWT console and during GWT compilation I'm getting warnings like it
is shown below.
Could anybody comment what's the cause of the warnings and how to
eliminate them?

- GWT 1.7.1
- Java 1.6

Thanks in advance

just a guess: maybe somewhere else in the code you use
MyClass<Something> someVar;
