配置详情：

基于 Jrebel 根文件夹的启动脚本中的以下行

export REBEL_HOME=[JRebel root folder]
export JAVA_OPTIONS="-agentpath:$REBEL_HOME/lib/libjrebel64.so -Drebel.remoting_plugin=true $JAVA_OPTIONS"

版本：

网络逻辑：12.2.1.2.0

杰瑞贝尔：7.1.2

谁能帮我过来？

解决方案

请尝试使用最新版本的 JRebel 而不是7.1.2。在https://zeroturnaround.com/software/jrebel/download/prev-releases/下载它。

如果由于某种原因结果仍然相同，请删除REBEL_HOME/bootcache 并重试。如果您仍然看到异常，请连同来自REBEL_HOME的jrebel.log一起写信至 support@zeroturnaround.com ，他们将能够帮助您。
