使用 Java 1.8.0_251 转换 XSL 时发生致命错误 [英] Fatal Error when transforming a XSL with Java 1.8.0_251

问题描述

在尝试转换样式表时，我收到来自 Java 1.8.0_251 的以下错误.然而，相同的样式表转换与 Java 1.8.0_241 没有任何问题.当行 tFactory.newTransformer(stylesheet); 时出现错误；被执行.

同样使用 xalan 2.7.2 而不是 Java 1.8.0._251 也能工作，但那个版本的 os xalan 真的很旧.

有人遇到过这种情况吗?如果是如何解决?

SimpleWorking04.xslhttps://drive.google.com/file/d/1OsOflQzGErvVFVsrmriqa0gbODS2查看?usp=sharing

如果您比较上述两个文件，则只是在 SimpleNotWorking04.xsl 中添加了一个空行，导致出现此错误.

注意不定位"后面的数字(例如不定位 10980:)将根据 XSL 内容而变化.

代码很简单，如下.

import javax.xml.transform.Transformer;导入 javax.xml.transform.TransformerFactory;导入 javax.xml.transform.stream.StreamSource;导入 javax.xml.transform.TransformerConfigurationException;导入 java.io.File;公共类 SimpleTest {/*** @param args 命令行参数*/公共静态无效主(字符串 [] args){尝试{StreamSource 样式表 = new StreamSource(new File("SimpleNotWorking04.xsl"));TransformerFactory tFactory =TransformerFactory.newInstance();Transformer Transformer = tFactory.newTransformer(stylesheet);}抓住(变压器配置异常tce){System.out.println("错误:"+tce.getMessage());}捕获(异常 e){System.out.println("错误:"+e.getMessage());}捕获(可扔的 t){System.out.println("错误:"+t.getMessage());}System.out.println("转换完成！！");}}

解决方案

这是 Java 8 251 版本中的一个错误.在向 Oracle 报告后，该问题已修复并随 Java 8 271 October 2020 版本一起发布.

When trying to transform the stylesheet I get the following error from Java 1.8.0_251. Yet the same stylesheet transform without any issues with Java 1.8.0_241. I get the error when the line tFactory.newTransformer(stylesheet); is executed.

Also using xalan 2.7.2 instead of the Java 1.8.0._251 works as well but that version os xalan is really old.

Has anyone come across something like this? If so how to solve it?

SimpleWorking04.xsl https://drive.google.com/file/d/1OsOflQzGErvVFVsrmriqa0gbODS2OWi5/view?usp=sharing

If you diff the two above files it's just one blank line added to the SimpleNotWorking04.xsl that gives this error.

NOTE the number after "Not targeting" (e.g. Not targeting 10980:) will change depending on the XSL content.

The code is simple and is as below.

import javax.xml.transform.Transformer;
import javax.xml.transform.TransformerFactory;
import javax.xml.transform.stream.StreamSource;
import javax.xml.transform.TransformerConfigurationException;
import java.io.File;

public class SimpleTest {

   /**
    * @param args the command line arguments
    */
   public static void main(String[] args) {
      try{
         StreamSource stylesheet = new StreamSource(new File("SimpleNotWorking04.xsl"));
         TransformerFactory tFactory =TransformerFactory.newInstance();  
         Transformer transformer = tFactory.newTransformer(stylesheet);
      }
      catch(TransformerConfigurationException tce) {
          System.out.println("ERROR:"+tce.getMessage());
      }
      catch(Exception e){
         System.out.println("ERROR:"+e.getMessage());
      }
      catch(Throwable t){
         System.out.println("ERROR:"+t.getMessage());
      }
      System.out.println("Done transformation!!");
   }

}

解决方案

This is a bug in Java 8 251 version. After reporting it to Oracle it was fix and released with Java 8 271 October 2020 release.
