Loading of model manually doesnšt work for me due to the reason I cannot
understand.

For example, I have two frameworks, one of which (second) is listed in the
Properties/Java Build Path of another (first).

When I try to load the missing model of the second framework for running
unit test of the first one I get the following exception:
