Question

我工作的应用程序的用户正在使用neo4j 2.1.1报告此特定异常。这似乎是零星的，难以复制。这是一个已知问题，还是与任何特定的误用或错误相关联？我很乐意提供有关如何重现这一点的更多信息，但我不能。

创建此堆栈跟踪的代码非常简单：

Node n = null;

try (Transaction tx = db.beginTx()) {           
    n = db.createNode();
    // Lots of extra code snipped here because it never makes it that far...
}

似乎在createNode()方法上抛出了异常：

SEVERE: Servlet.service() for servlet [Jersey REST Service] in context with path [/plus] threw exception
org.neo4j.kernel.impl.persistence.ResourceAcquisitionFailedException: TM encountered an unexpected error condition.

        at org.mitre.provenance.db.neo4j.Neo4JStorage.store(Neo4JStorage.java:1101)

（这里有大量与servlet相关的异常消息）

在底部，有这样的：

Caused by: javax.transaction.RollbackException: Tx status is: STATUS_MARKED_ROLLBACK
        at org.neo4j.kernel.impl.transaction.TransactionImpl.enlistResource(TransactionImpl.java:191)

自2.1.1以来已经应用了很多修复，因此请确保在最新的稳定版本（截至今天的2.1.4）上运行。如果问题仍然存在于2.1.4，请考虑在https://github.com/neo4j/neo4j/issues/new
