你用的第三方库com.hankcs.hanlp.dictionary.CoreDictionary  CoreDictionary.java里有一个辞典加载失败时做一个System.exit(-1)的系统调用。  ES使用了 Java Security Manager来限制第三方库做不安全的系统调用,所以这个System.exit(-1)就被禁止了。 
 
解决方法一个是更改这个第三方库,在异常的时候不要掉用system.exit,或者为这个库加一个白名单(有安全隐患,不建议这么做)。

某些代码应该放在doPrivileged方法,你可以参考一下plugin-authors-jsm
SecurityManager sm = System.getSecurityManager();
if (sm != null) {
// unprivileged code such as scripts do not have SpecialPermission
sm.checkPermission(new SpecialPermission());
}
AccessController.doPrivileged(
// sensitive operation
);
