Massive parallel execution of parametrised CorpusTest junit tests revealed race condition in `ClassHierarchyImpl.CachedClassHierarchyResolver::getClassInfo`.
The race condition may skip calculation of the ClassHierarchyInfo. In this specific case it caused SegmentScope not being identified as an interface and verify error on assignability between declared method return type and actual returned type has been emitted by the test. Proposed patch fixes the race condition in `ClassHierarchyImpl.CachedClassHierarchyResolver::getClassInfo`. Please review.
