The message VM_getObjectClassFromKnownObjectIndex is sent by the server from the getObjectClassFromKnownObjectIndex(comp, knot_index) frontend call to retrieve the class of the object stored in the known object table at the given index. In many cases the known object table has this information already cached. This commit reimplements the frontend query `getObjectClassFromKnownObjectIndex(TR::Compilation *, TR::KnownObjectTable::Index)` so that it calls getObjClassInfoFromKnotIndex() which in turn takes advantage of the existing cache in the known object table.
