Like a comment in the issue above, if I comment out ZfcUserDoctrineORM\Entity\User from ZfcUserDoctrineORM's autoload_classmap and then it works fine.
It would seem that Zend is loading the class using the classmap, but then doctrine isn't able to find it, and attempts to load again by cycling through registered autoloaders.
I get a "Fatal error: Cannot redeclare class ZfcUserDoctrineORM\Entity\User" when trying to generate database scheme from the command line.
I see an identical issue marked as resolved here: https://github.com/ZF-Commons/ZfcUserDoctrineORM/issues/2
