NullPointerException on simple queries about orientdb-gremlin HOT 4 OPEN

Further investigation seems to indicate the issue occurs when records are removed from the database. The traversal still tries to iterate through missing vertices which causes the null pointers. I've tracked it back farther to OrientVertex:65. The call to .rawIterator() appears to return deleted vertices. Perhaps the call should be to .iterator() instead?

In addition to calling .iterator() as bblonski suggested, I added a filter to ignore any nulls while streaming over the collection. This appears to have fixed the issue we were having.

Hi @bblonski

Is this issue still valid? I checked the code but too many things have changed, so the patch from @ken-at-sri cannot be applied anymore

Thanks

Ops, sorry, checked the wrong implementation (TinkerPop2), assigning to @maggiolo00 for a check
