一般地，这类错误是自编函数出错导致的系统错误的。与JAVA平台无关。根据错误日志文件，我们可以查看出错的具体原因。

下面代码片段是一次错误生成的日志文件：

根据这个文件，我们可以清楚地看到这个错误是因为使用动态库split_sentence_jni.dll导致的，但是，错误的发生不是因为动态库split_sentence_jni.dll有问题，而是在使用相关函数时出错，例如：

List sents = NLPfun.splitSentence(content);

在使用上述函数时，将null赋值给了content，导致程序运行出错！

同理，下述错误是由于句法分析函数接受了过长的句子的输入，导致句法分析出错，这个错误是parser.dll本身的错误。为了避免错误的发生，parser处理函数的输入句子最好小于200.
