退回weblogic服务器

错误： 当我试图反弹服务器时，我收到了以下错误

配置详细信息：

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：

Weblogic：12.2.1.2.0

Jrebel：7.1.2

任何人都可以帮助我过来吗？

Answer 1

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。

如果由于某种原因结果仍然相同，也请删除 REBEL_HOME / bootcache 并重试。如果您仍然看到例外情况，请写信至support@zeroturnaround.com以及 jrebel.log 来自 REBEL_HOME ，他们将能够帮助你。

Jrebel没有使用weblogic 12.X
