Hi Samuel,
JUnit can/will run tests in a different order each time. So if your tests
depend on something else having happened (EOF getting fully initialized, some
other test running first) you will see random failures like this. I think it
an/will run tests in multiple threads too (I use both JUnit and TestNG and
sometimes mix up their features :-) so concurrency can also cause problems like
this.

Those are likely to be OK.

I am guessing you need that model for the permissions testing. This is likely
a problem.

Do you have multiple EOF stacks (multiple EOObjectStoreCoordinators)? You
could be using default* methods that only work with the default stack. Is
there a stack trace for that last one to show where duplication model loading
is having?

I think that means a model is being used that is not yet in an EOModelGroup.
