 * A version of java.io.Externalizable to be able to compile shared Java code that uses it.
 * <p>
 * Externalization is not supported in GWT. Shared classes that implement the interface can
 * mark the corresponding methods as {@code @GwtIncompatible} but the interface still needs to
 * exist for the code to compile.
 * <p>
 * The implementation has to mark all the overriding methods as {@code @GwtIncompatible}.
