This is true for example for this class:

class Test {

    private final static ThreadLocal<Test> local = new ThreadLocal<Test>(){

        @Override

        protected Test initialValue(){

            return new Test();

        }

    };

}

In this case the org.jboss.weld.util.reflection.Reflections#isStatic(java.lang.Class<?>) method returns true for the anonymous type, which looks bit weird.
