java - Neo4j 社区版本 2.0 失败

Question

我收到了这个错误：

我在 Linux 64 机器上运行 neo4j，发行版 Fedora 19；爪哇版：

$ java -version
java version "1.7.0_45"
Java(TM) SE Runtime Environment (build 1.7.0_45-b18)
Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)

---

环境变量：

JAVA_HOME="/usr/java/jdk1.7.0_45"
CLASSPATH=.:$JAVA_HOME
PATH=$PATH:$HOME/.local/bin:$HOME/bin

我无法弄清楚发生了什么。有什么帮助吗？
