由以下原因引起的org.w3c.dom.ls.LSException:java.lang.NegativeArraySizeException

我必须保存一个XML文件。我使用的是DOm，文件很大，大约1,3 Gb。为此，我使用以下代码：

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();
    }
}

当我尝试保存小XML文件时，我没有问题，但当我尝试保存大文件时，我会收到下一个异常：

我使用Xerces 2.11库。

你能帮助我吗？谢谢

Xerces2Java2.11.0

依赖于

serializer.jar

。在这个库中，您可以找到

org.apache.xml.serializer.SerializerBase

类

代码（在第958行）表明，即使长度是负数（由于bug），那么数组总是用正数创建的。事实上，a正在被提出，这是

如果应用程序尝试创建大小为负的数组，则引发

表示由

长度*2+1

计算引起的错误。我认为这是因为提供给DOM解析器的XML文档非常大

我会考虑使用SAX解析器来查看比较。

听起来像XECES中的一个bug。联系他们的邮件列表
