问题描述

如何在使用JVMTI代理的情况下解决 java结果1的1种特殊风味？

How to resolve 1 particular flavor of 'java result 1' in the context of using JVMTI agents?

推荐答案

我在我的环境中解决了一个问题：

Here's how I resolved an issue in my context:

服务器通过ANT脚本运行，并且jvm配置了代理（以下属性名称 agentfile与一个值相关联）指向代理库）

The server is run through an ANT script with jvm configured with an agent (the property name 'agentfile' below is associated with a value pointing to the agent library)

现在，我会收到错误信息'java result每当服务器运行时都为1'，没有任何实际错误的指示。

Now, I would get the error 'java result 1' whenever the server was run, without any indication of the actual error.

这是调试此问题的方式。
1）代理已关闭（即，以上两行已被注释掉）。
2）然后，在运行ANT时，清楚地显示了实际的错误消息-问题是：缺少类文件。该错误已被代理吞噬，因为它是低级C代码，并且看起来只是加载无法找到的类并引发Java错误。

Here's how this issue was debugged. 1) The agent was turned off (i.e.) the above 2 lines were commented out. 2) Then when ANT was run, the actual error message was clearly shown - the problem was: a class file was missing. This error was being eaten by the agent, since it is low level C code and just looks to load a class that it cannot find and throws the Java error.

经验教训：如果您有代理，请先将其关闭，然后再运行您的ANT-这可能会引发出现错误的原因。当然，这是Java结果1错误引起注意的许多情况之一。

Lesson learnt: if you have an agent, turn it off and then run your ANT - it may throw up the reasons for error seen. This is of course one of many scenarios noticed for the java result 1 error.
