neo4j-Gremlin-plugin StackOverflow using tree() pattern

Question

Я пытаюсь выполнить запрос дерева по образцу. Однако он всегда дает мне исключение StackOverflow. Круги эти два документ:

http://tinkerpop.incubator.apache.org/docs/3.0.1-incubating/#tree-step https://github.com/tinkerpop/gremlin/wiki/Tree-Pattern

Чтобы воспроизвести ошибку:

Neo4j 2.3.2
Neo4j-гном-плагин
на: Ubuntu 14,04

Создайте график:

GET http://localhost:7474/tp/gremlin/execute?script=g.addV("Label1").property("name", "Mark").as("v1").addV("Label2").property("street", "myStreet").as("v2").addV("Label3").property("number", 11).as("v3").addE("r1").from("v1").to("v2").addE("r2").from("v2").to("v3")

Perorm запрос

GET http://localhost:7474/tp/gremlin/execute?script=g.V().out("r1").out("r2").tree()

Можете ли вы помочь мне копаться в этой proble м? Большое спасибо

Answer 1

Это скорее всего проблема TinkerPop: TINKERPOP-732 (который был на самом деле давно Jackson issue, что совсем недавно была исправлена ​​в 2.7.x) и должны быть установлены для выпуска 3.1.2.
