Config详细信息:

启动脚本中的以下行是基于J反叛根文件夹的

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

J反演: 7.1.2

有人能帮我过来吗？

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/下载它。

如果由于某种原因，结果仍然相同，也可以删除REBEL_HOME/bootcache并重试。如果您仍然看到异常，请写信给support@zeroturnaround.com和来自REBEL_HOME的jrebel.log，他们将能够帮助您解决问题。
