Summary: HasContainer should allow a null key Key: TINKERPOP-2727 URL: https://issues.apache.org/jira/browse/TINKERPOP-2727 Project: TinkerPop Issue Type: Improvement Components: process Affects Versions: 3.5.2 Reporter: Florian Hockmann TINKERPOP-2605 changed {{null}} semantics to allow {{null}} as an argument in more places so that {{has(null)}} should not throw a NPE any more and instead filter all traversers out. {{HasContainer}} however still throws a NPE if the {{key}} is {{{}null{}}}. I discovered this when trying to update JanusGraph [as that folds in a {{HasContainer}} like this|https://github.com/JanusGraph/janusgraph/blob/4246d49cee46d549d752515f3956cd2d59f1fd0a/janusgraph-core/src/main/java/org/janusgraph/graphdb/tinkerpop/optimize/step/HasStepFolder.java#L266] which leads to the NPE and thus failing tests. The same behavior can also be produced with just TinkerGraph and for example the following traversals: {code:java} g.V().has(null, 1) g.V().has(null, P.neq(null)){code} -- This message was sent by Atlassian Jira (v8.20.1#820001)
