getRelationships()上neo4j IndexOutOfBoundsException的原因 [英] Cause of neo4j IndexOutOfBoundsException on getRelationships()

这是在neo4j版本2.3.0-M02

为什么这样的代码....

Why might this code ....

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

...导致此堆栈跟踪?

推荐答案

您应该升级到Neo4j 2.3.0-M03.

You should upgrade to Neo4j 2.3.0-M03.

里程碑发布趋于不稳定，并且您使用的是旧版本.众所周知，M02有错误，许多错误已在M03中修复.

Milestone releases tend to be unstable and you are using old one. It is known that M02 has bugs, and lot of them are fixed in M03.

因此，请升级并检查它是否适合您.

So, upgrade and check if this works for you.
