一分钟前工作的方法的java.lang.VerifyError [英] java.lang.VerifyError on method that worked a minute ago

问题描述

提前道歉，但我以前从未见过这个错误，也不知道要包括什么。我正在使用NetBeans并突然开始收到此错误：

Apologies in advance but I have never seen this error before and don't know what to include. I am using NetBeans and suddenly began getting this error:

Exception in thread "AWT-EventQueue-0" java.lang.VerifyError: (class: market/CostOperations, method: <init> signature: ()V) Constructor must call super() or this()

我不知道发生了什么。我甚至没有修改market / CostOperations。

I have not a clue what happened. I didn't even modify market/CostOperations.

这里是构造函数：

public CostOperations() throws ParserConfigurationException, SAXException, IOException {

        //Open the xml file
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        f = new File(dbName);
        doc = builder.parse(f);
        System.out.println(f.canWrite());

        //Create the XPath
        XPathFactory xpfactory = XPathFactory.newInstance();
        path = xpfactory.newXPath();

    }

在调试模式下我得到这个：

In Debug Mode I get this:

debug:
Have no FileObject for C:\Program Files (x86)\Java\jdk1.6.0_20\jre\lib\sunrsasign.jar
Have no FileObject for C:\Program Files (x86)\Java\jdk1.6.0_20\jre\classes

我只需知道导致错误的原因以及解决方法。谢谢！

I just need to know what is causing the error and how to fix it. Thanks!

推荐答案

A VerifyError 表示字节码无效，哪些点编译问题。我会尝试重建一切，希望它消失，但否则你应该提交一个错误。字节码是通过 invokenonvirtual superclass /< init>（）V 手动调用超类构造函数所必需的，但是你不需要添加 super （）; 在源代码中，编译器应该处理

A VerifyError means the bytecode is invalid, which points to a compiler problem. I would try rebuilding everything in the hopes that it goes away, but otherwise you should file a bug. The bytecode is required to call the superclass constructor manually via invokenonvirtual superclass/<init>()V, but you shouldn't need to add super(); in the source, the compiler should handle that
