Comment (by ikispal@…):

 What is even worse:
 if the future returned by then() is not void, then:

 *  the first call of its get() will call the continuation a second time
 (as described above) and will return with the result of this erroneous
 second invocation!

 * the second call of its get() will return with an empty (default
 constructed?) value!
