Question

这发生在neo4j版本2.3.0-M02

中

为什么这个代码......

Iterable<Relationship> rels = node.getRelationships( ... any various args ... );
for (Relationship rel : rels) {
    // Some computation
}

...导致这个堆栈跟踪？

更新

Answer 1

您应该升级到Neo4j 2.3.0-M03。

里程碑版本往往不稳定，你使用旧版本。众所周知，M02有缺陷，很多都是固定在M03中。

因此，请升级并检查这是否适合您。

getRelationships（）上neo4j IndexOutOfBoundsException的原因
