带调试模式的 jrebel 无法更新类答案

【问题标题】：jrebel with debug mode can't update class带调试模式的 jrebel 无法更新类
【发布时间】：2020-02-14 02:10:03
【问题描述】：

我用 jrebel 的调试模式启动了这个项目。当我更新类时，jrebel 抛出以下日志异常。尽管我没有对类进行任何更改，但我只是添加了一个空格。在启动模式下启动是正常的。

这让我很困惑。 jrebel和debug模式有冲突吗？我用的是最新版的jrebel，虚拟机oracle jrockit 1.6

【解决方案1】：

是的，JRebel 应该使用这些调试选项。我不确定您为什么会收到这些错误。我需要查看这些日志以了解正在发生的事情。

如果您想解决它，请将您的日志发送至 support@jrebel.com，我将非常乐意为您提供进一步帮助。

【解决方案2】：

我叫 Curtis Johnson，是 Perforce 的 JRebel 团队的一名工程师。这似乎是您的应用程序中的某种错误，可能与 JRebel 直接相关，也可能不相关。您最好与我们的支持团队合作解决此问题。如果您可以将 JRebel 日志 (instructions here) 发送到 support@jrebel.com，我们可以帮助您解决此问题。

【讨论】：

你好柯蒂斯，我检查了问题的原因。当我从命令行运行jrebel时，当我添加调试参数时，就会出现这个问题。如果调试参数去掉，就会恢复正常。参数如下：-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5007
