#summary GWT Compiler + ListGrid + com.gwtent.reflection.client compile failure

I'm getting the following GWT compile failures:

I have isolated the failure to a very simple test case. This is a GWT compile 
time failure.

For the test case to fail all of the following needs to be true.

* A class implements the interface com.gwtent.reflection.client.Reflection
* A private field of type ListGrid is declared (although never referenced).
* The method getClass() is called in the constructor.

If one or more of these three elements is not present the GWT compiler failure 
does not occur.

----

Here is the code that causes the failure:

{{{
public class GWTEntTest implements com.gwtent.reflection.client.Reflection {

    private com.smartgwt.client.widgets.grid.ListGrid listGrid;

    public GWTEntTest() {
        getClass();
    }
} 
}}}

For a little more background I researched the source code of the interface 
com.gwtent.reflection.client.Reflection. This interface has no methods and only 
uses the annotation com.gwtent.reflection.client.Reflexible.

Here is the code for com.gwtent.reflection.client.Reflection (with comments 
removed)

{{{
@Reflectable(fieldAnnotations = true, relationTypes = true, superClasses = 
true, assignableClasses = true)
public interface Reflection {

}
}}}

Here is the code for com.gwtent.reflection.client.Reflexible (with comments 
removed)

{{{
import java.lang.annotation.ElementType;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Target;

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.TYPE)
public @interface Reflectable {
    public boolean classAnnotations() default true;
    public boolean fields() default true;
    public boolean methods() default true;
    public boolean constructors() default true;
    public boolean fieldAnnotations() default true;
    public boolean relationTypes() default false;
    public boolean superClasses() default false;
    public boolean assignableClasses() default false;
}
}}}

It’s not possible for me to determine the root cause from this. It could be 
in any combination of the GWT compiler, 
com.smartgwt.client.widgets.grid.ListGrid, and com.gwtent.reflection.client 
library.
