Java工作区中Ant构建ArrayIndexOutOfBoundsException

我正在尝试用Ant构建脚本构建一个Web应用程序。应用程序有许多模块，编译两个项目后，生成失败，并出现以下错误日志：

[javac]编译器（1.4.2）中发生异常。请在检查错误列表中是否有重复的错误后，在Java开发者连接（）中提交一个错误。在报告中包括您的程序和以下诊断。非常感谢。 [javac]java.lang.ArrayIndexOutOfBoundsException:25459

这是一个Java4应用程序。我们已经尝试过用Ant版本1.7和1.8构建它，但都失败了，出现了相同的错误

以下是完整的堆栈跟踪：

[javac] An exception has occurred in the compiler (1.4.2). Please file a bug at the Java Developer Connection (http://java.sun.com/cgi-bin/bugreport.cgi)  after checking the Bug Parade for duplicates. Include your program and the following diagnostic in your report.  Thank you.

经过两天的努力，终于找到了问题。这是由JAR中的重复.class文件引起的。这是非常奇怪的，因为我看到ant任务在打包JAR时复制了重复的.class文件（在详细模式-v中有警告）。以下是构建脚本文件中的片段，它是罪魁祸首：

<jar destfile="${dir_dest}" manifest="${dir_src}/META-INF/MANIFEST.MF">
    <fileset dir="${dir_dest}" />   
    <fileset dir="${dir_src}" excludes="**/*.java"/> 
</jar>

脚本在我删除后成功运行：

<fileset dir="${dir_dest}" />

以下链接帮助我解决了这个问题：

请花一分钟时间从其他人的角度看你的文章。你的问题是什么？你有没有跟踪链接，并试图找出这是否是一个报告的错误？考虑一些人可以从一个堆栈跟踪通知你很少的上下文信息。你可能得缩小范围，给我们一个帮助的机会。也许可以尝试一种“分而治之”的方法：产生错误的最小构建量是多少？谢谢Martin。我试图提供问题的狭隘观点，但这不是一个报告的bug。有时，堆栈跟踪是非常有用的，如果有人遇到类似的问题，他们会立即猜测。谢谢你的建议，我会听从你的建议。经过两天的努力，我终于找到了解决方案，并将发布给其他人参考。很高兴你找到了它-看起来是一个棘手的发现！
