在Java代码中设置-noverify标志 [英] Set -noverify flag in java code

问题描述

我想通过Java代码将-noverify设置为VM参数.我找不到在线任何资源来帮助解决这个问题.

I would like to set -noverify as a VM argument through java code. I could not find any resource online to help with this.

如果我使用System.setProperty(..,..)，该如何设置值或键?

If I use System.setProperty(..,..) , what do I set as the value or perhaps the key?

我尝试使用System.property("Xverify","none")，但这似乎不起作用.

I have tried using System.property("Xverify","none") but this doesn't seem to work.

注意:这只是为了运行一些测试用例.由于这个问题，我正在关闭字节码验证-链接

Note: This is just to run some test cases. I am turning off byte code verification because of this issue - link

谢谢.

推荐答案

让我总结一下此答案中的评论.

Let me summarize comments in this answer.

• 关闭字节码验证很危险，尤其是当您知道应用程序抛出VerifyError时.这意味着应用程序生成无效的字节码，并且当JVM执行它时，结果是不可预测的.例如，JVM可能会崩溃，例如这个问题.
• 没有合法的方法以编程方式关闭字节码验证.否则，这将是严重的安全漏洞，允许在没有显式权限的情况下运行不安全的代码.
• 您提到的PowerMock问题的链接确认存在 Javassist库中的错误.解决此问题的正确方法是，更新到已修复此错误的Javassist新版本.

• It is dangerous to turn the bytecode verification off, especially when you know the application throws VerifyError. This means that the application generates invalid bytecode, and when JVM executes it, the results are unpredictable. For example, JVM may crash like in this question.
• There is no legal way to turn the bytecode verification off programmatically. Otherwise this would be a serious security breach that allows to run unsafe code without explicit permissions.
• The link to PowerMock issue you've mentioned confirms that there was a bug in Javassist library. The right way to solve the issue is to update to newer Javassist version where this bug has been fixed.
