org.w3c.dom.ls.LSException引发：java.lang.NegativeArraySizeException

我必须保存一个XML文件。我使用DOm，文件很大，大约为1,3 Gb。这样做我用下面的代码：org.w3c.dom.ls.LSException引发：java.lang.NegativeArraySizeException

public void guardarDocumentoXML() throws FileNotFoundException, IOException { 
    DOMImplementationLS ls = (DOMImplementationLS)documentoXML.getImplementation(); 
    LSSerializer ser = ls.createLSSerializer(); 
    LSOutput out = ls.createLSOutput(); 
    out.setEncoding("UTF-8"); 
    FileOutputStream output = new FileOutputStream(nombrearchivo); 
    try { 
     out.setByteStream(output); 
     ser.write(documentoXML, out); 
    } finally { 
     output.close(); 
    } 
}

当我试图保存小XML文件我没有问题，但是当我尝试保存一个巨大的文件我收到一个异常：

我使用Xerces 2.11库。你能帮我吗？谢谢

听起来像是在xerces中的错误。在他们的邮件列表上联系他们 – rolfl 2013-04-30 12:30:37

Xerces2 Java 2.11.0取决于serializer.jar。在这个图书馆你会发现org.apache.xml.serializer.SerializerBase课程。

代码m_charsBuff = new char\[length * 2 + 1\];（在线958）表明即使长度在某种程度上是负面的（由于bug），那么该数组总是会创建一个正数。 NegativeArraySizeException正在提出的事实是

如果应用程序尝试创建负大小的数组，则会抛出此异常。

暗示由length * 2 + 1计算引起的integer overflow。我相信这是因为提供给DOM解析器的XML文档是非常大。

我会考虑使用SAX解析器 - 请参阅What is the difference between SAX and DOM?进行比较。
