Current implementation of calls with super qualifier relies on
invokespecial, which has some more constraints than regular virtual
invocations. When those constraints aren't met, accessors are needed.
In case of the same class defined in different modules they contain
different descriptors instances in their scope that might lead
to failing assertion in findConcreteSuperDeclaration
because there are overridden from different modules
It might happen even in the compiler because of different built-in modules
defined for sources-module and for dependencies' one
