JRebel 6.4.6插件在IDEA 16和Tomcat 9中不起作用

Question

I downloaded jrebel plugin in IDEA 16 and got a license. When I run my application with "jrebel run" button, I got the following output:

2016-07-07 13:40:18 JRebel:

2016-07-07 13:40:18 JRebel:  

and this

2016-07-07 13:40:20 JRebel: Directory 'E:\IdeaProjects\baobiao\target\classes' will be monitored for changes.
2016-07-07 13:40:20 JRebel: Directory 'E:\IdeaProjects\baobiao\src\main\webapp' will be monitored for changes.

but when I test modify a spring requestmapping annotation, it didn't work. The server output didn't show "JRebel: reloading class ..." word. So I opened the jrebel.log and there was an error in it:

I have googled this question for a long time and still have no idea about it, is there anyone can help? Thanks very much!

Answer 1

Temporary workaround would be to take offline lease , but to troubleshoot why did the exception occur, send trace-level jrebel.log (add -Drebel.log=trace to server JVM arguments) to support@zeroturnaround.com along with link to this thread. See manual if you have any questions about logs.
