GwtIncompatible (Guava: Google Core Libraries for Java HEAD-jre-SNAPSHOT API)

@Retention(CLASS)
@Target({TYPE,METHOD,CONSTRUCTOR,FIELD})
@Documented
@GwtCompatible
public @interface GwtIncompatible
```
The presence of this annotation on an API indicates that the method may not be used with the Google Web Toolkit (GWT).
This annotation behaves identically to the @GwtIncompatible annotation in GWT itself.

String value
```
    Describes why the annotated element is incompatible with GWT. Since this is generally due to a dependence on a type/method which GWT doesn't support, it is sufficient to simply reference the unsupported type/method. E.g. "Class.isInstance".
    As of Guava 20.0, this value is optional. We encourage authors who wish to describe why an API is @GwtIncompatible to instead leave an implementation comment.
