将文档添加到Lucene索引时出现ArrayIndexOutOfBounds异常（v 5.1.0）

在向索引中添加了几个文档之后，我不断收到ArrayIndexOutOfBounds异常。我有一个线程可以跨多台机器将文档添加到索引中。 我不确定这是否与我如何向文档中添加字段有关。“文本”可以是任意长度

public static void CreateIndex(){
    int count = 0;
    try {
        IndexWriters.initIndexWriters(); //these are located on different machines on the network

        int whichIndex = 0;

        FileInputStream fis = new FileInputStream(Constants.MY_XML);
        BufferedReader t = new BufferedReader(new InputStreamReader(fis, "UTF-8"));

        String title = "";
        String articleId = "";
        String str;

        while ((str = t.readLine()) != null)
        {
                title = str.replace("<title>", "").replace("</title>", "").trim();
                str = t.readLine();
                articleId = str.replace("<id>", "").replace("</id>", "").trim();
                str = t.readLine();
                text = str.replace("<text>", "").replace("</text>", "").trim();

                Document lDoc = new Document();

                Field id = new TextField("id", articleId, Field.Store.YES);
                Field title = new TextField("title", title, Field.Store.YES);
                Field text = new TextField("text", text.toString(), Field.Store.YES);
                Doc.add(id);
                Doc.add(title);
                Doc.add(text);

                IndexWriters.indW[whichIndex].addDocument(Doc);  //exception thrown here after adding couple of documents

                whichIndex = (whichIndex+1)%(Constants.NUMNODES*Constants.PER_NODE_INDEXES_COUNT);
                ++count;
                }
                articleId = "";
                text = null;
                title = "";
            }
            }
        }
        IndexWriters.closeWriters();

    }catch (IOException e) {
        e.printStackTrace();
    }catch( Exception e){
        e.printStackTrace();
    }
}

那么，您的代码中的假设是：

Constants.NUMNODES*Constants.PER_NODE_index_COUNT

等于（或小于）

IndexWriters.indW.length

看来这个假设是不正确的

---

（这里也有一堆无关的

}

s，但是如果它编译了，我会假设这只是你在这里编辑发布时留下的东西）

好吧，你的代码中的假设是：

Constants.NUMNODES*Constants.PER_NODE_index_COUNT

等于（或小于）

IndexWriters.indW.length

看来这个假设是不正确的

（这里也有一堆无关的

}

s，但如果它编译了，我想这只是你在这里编辑帖子时留下的东西）

实际常数。NUMNODES*Constants.PER_NODE_index_COUNT等于IndexWriters.indW.length.实际常数。NUMNODES*Constants.PER_NODE_index_COUNT等于IndexWriters.indW.length。
