Good question. Fortunately Charles F. Schatz already pointed
this out before the 2.2 release, so since then there are two
ways to detect the referenced type:

1. Use the Mibble type name tracking:
     MibType.hasReferenceTo("Counter64")

2. Use the type tag for Counter64 [APPLICATION 6]:
     MibType.hasTag(MibTypeTag.APPLICATION_CATEOGORY, 6);

For SNMP I guess this is often a better method to use than
to test with instanceof since only a few base types are
really used.

Hope this answers your question!
