Cause of neo4j IndexOutOfBoundsException on getRelationships()

问题

This is happening in neo4j version 2.3.0-M02

Why might this code ....

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

... cause this stack trace ?

Update:

Issue #5691 on Github
Same bug again in version 2.3.0

回答1:

You should upgrade to Neo4j 2.3.0-M03.

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.

So, upgrade and check if this works for you.
