+ * Java counter-part of AwWebContentsViewDelegate. Used only for handling
+ * context menu callback currently.

nit: delete second sentence. (too easy to go out of date)
what would be useful is to add a note on ownership model. native counterpart is
owned by the underlying WebContents, this java side is retained so long as the
associated AwContents instance is valid.
