Stanford nlp 斯坦福-segmenter-2015-12-09碰撞

新的stanford-segmenter-2015-12-09在使用OpenJDK的Ubuntu 14.04 64位上崩溃：

tahoar@library0:~$ java -version
java version "1.7.0_91"
OpenJDK Runtime Environment (IcedTea 2.6.3) (7u91-2.6.3-0ubuntu0.14.04.1)
OpenJDK 64-Bit Server VM (build 24.91-b01, mixed mode)

下面是示例脚本的输出：

./segment.sh ctb test.simp.utf8 UTF-8 0

(CTB):
File: test.simp.utf8
Encoding: UTF-8

在使用Oracle Java的Windows 10上，它运行良好：

C:\Users\tahoar>java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b18)
Java HotSpot(TM) Client VM (build 25.66-b18, mixed mode, sharing)

对JRE for Linux有什么建议吗？

您正在使用为Java 1.8编译的代码，并在Java 1.7.DOH上运行它！Stanford Segmenter主页上说，“系统需要安装Java1.8+。”我的糟糕！
