- Deprecated Constructors
  Constructor and Description
  org.mozilla.javascript.Context() this constructor is deprecated because it creates a dependency on a static singleton context factory. Use `ContextFactory.enter()` or `ContextFactory.call(ContextAction)` instead. If you subclass this class, consider using `Context.Context(ContextFactory)` constructor instead in the subclasses' constructors.
