This rule prohibits publishing a reference to a partially initialized member object instance before initialization has concluded. It specifically applies to safety in multithreaded code. The related rule TSM01-J. Do not let the ( this ) reference escape during object construction prohibits the this reference of the current object from escaping its constructor. Also see OBJ11-J. Be wary of letting constructors throw exceptions for some consequences of publishing partially-initialized objects even in single-threaded programs.

Consequently, the reference to the helper instance should remain unpublished until the Foo class's constructor has completed. See rule TSM01-J. Do not let the ( this ) reference escape during object construction for additional information.
