自己训练的pos.bin不能加载

[tianjiangtao]

Describe the bug 自己训练的crf模型文件，pos.bin不能加载，但是同时生成的pos.bin.txt就可以加载成功。

Code to reproduce the issue

CRFPOSTagger tagger = new CRFPOSTagger(null); // 创建空白标注器
//        tagger = new CRFPOSTagger(PKU.POS_MODEL); // 加载
         tagger = new CRFPOSTagger("/root/repo/hanlp-java/HanLP/data/test/pos.bin"); // 加载
        System.out.println(Arrays.toString(tagger.tag("他", "的", "希望", "是", "希望", "上学"))); // 预测
        AbstractLexicalAnalyzer analyzer = new AbstractLexicalAnalyzer(new PerceptronSegmenter(), tagger); // 构造词法分析器
        System.out.println(analyzer.analyze("李狗蛋的希望是希望上学")); // 分词+词性标注

报错如下： java.lang.ArrayIndexOutOfBoundsException: 1677721600

Describe the current behavior 100%出错

Expected behavior 能正常加载pos.bin

但是使用相同的命令加载data-for-1.7.zip中带的/data/model/crf/pku199801/pos.txt.bin就可以成功加载
