 All these complications around varargs, including more eg [https://github.com/mrocklin/multipledispatch/issues/72 around dispatching vararg-typed methods] led us to currently not support varargs.
 
+==== @Nonnull
+Java variables like {{{String val}}} can contain a null value, and functions like {{{String f() { ... } }}} can return null. Therefore they are translated to {{{val:Optional[str]}}} and {{{def f(self)->Optional[str]}}}.
+You can annotate the java code with @Nonnull (from {{{javax.annotation.Nonnull}}}) to indicate the value/return value will not be null, like this
+{{{@Nonnull String val}}} or {{{@Nonnull String f() { ... } }}}.
+
+Note that Nonnull is NOT inherited by subclasses. Therefore the annotation may have to be repeated in the derived classes.
+
 ==== More notes:
 * some classes like {{{Arrays}}} or {{{Override}}} do not have a direct python equivalent. calls to static functions in these classes can still be translated.
