             * tree viewer (StructuredViewer/AbstractTreeViewer) which tries
             * to restore the selection even after a call to setInput (which
             * can change the content of the viewer totally). The problem
             * is that the tree viewer seems to buffer the objects
             * (HierarchyLevels) which are selected before the call to
             * setInput and then tries to restore the selection by looking
             * for the elements in the content provider of the viewer, which
             * includes calls to ITreeContentProvider.getParent which in
             * turn calls TestSessionContainer.getParentOfHierarchyLevel of
             * the newly set (via setInput) TSC. The latter doesn't like
             * getting requests for HierarchyLevels which don't belong to
             * its test session container (they belong to the old TSC which
             * was active before the call to setInput) and throws an
             * exception.
