Incoming references in the reference view show compact paths for for some well-known collections with an
internal reference structure. For linked lists, the "collection content" reference shown in the screen shot points
directly from the linked list to the list item. If you search for paths to garbage collector roots, the found paths can
be interpreted much more clearly that way.
Compact paths are also shown for hash maps and tree maps>. This is especially important in the cumulated incoming
reference view, because the internal reference structure of those collections could fragment collection content
into many blocks, thereby preventing a comprehensive analysis of the incoming references.
Also, hash maps are very common in reference chains and the "map key" and "map value" nodes are much more descriptive
than the internal structure.
