-----------------------------------------
Summary: Bad interaction of long-typed vertex properties with
TinkerGraph indexes
Key: TINKERPOP-1484
URL: https://issues.apache.org/jira/browse/TINKERPOP-1484
Project: TinkerPop
Issue Type: Bug
Components: tinkergraph
Affects Versions: 3.2.2, 3.2.3
Environment: macOS Sierra (v10.12), jdk 1.8.0_102-b14
Reporter: Florin Mihaila
In graphs with indexed properties, queries fail on certain vertices (but
not all) with properties of type long.
The following code reproduces the bug:
{noformat}
$ cat bug.groovy
graph = TinkerGraph.open()
graph.createIndex('other', Vertex.class) // (A)
graph.createIndex('prop', Vertex.class) // (B)
v = graph.addVertex()
v.property('prop', (long)1)
v.property('other', 0)
v = graph.addVertex()
v.property('prop', 12345678910)
v.property('other', 1)
g = graph.traversal()
{noformat}

gremlin> g.V().valueMap()

==>[other:[1],prop:[12345678910]]
gremlin> g.V().has('prop', 1) // (1)
gremlin> g.V().has('other', 0).has('prop', 1) // (2)
==>v[0]
gremlin> g.V().has('prop', 12345678910) // (3)
==>v[3]
gremlin>
{noformat}
Observations:
1. The node is not found, although it's there.
2. The node _is_ found as long as the graph is queried of another indexed
property first.
3. The node _is_ found if the property value is wider than an int.
Variations:
v1. If the 'other' property is not indexed (line A), query (2) fails.
v2. If the 'prop' property is not indexed (line B), all queries succeed!
Tested on freshly built tinkerpop distributions, versions 3.2.2 and 3.2.3.
