我已经完成了此负载测试方案，然后成功使用Neo4j 1.8.

I already done this load test scenario back then using Neo4j 1.8 with success.

它是否与启动服务器时收到的警告有关.

Is it can be related to the warnings I get when starting the server..

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
WARNING! You are using an unsupported Java runtime. Please use JDK 6.

两个版本之间的配置是否有所更改?发生这种异常的原因是什么?

Is anything changed in the configurations between the versions? what can be the reason for that kind of exception?

谢谢.
