com/intellij/rt/debugger/agent/DebuggerAgent : Unsupported major.minor version 51.0

Answered

Hello.

I'm using weblogic plugin in idea ultimate,  starting my weblogic 10.3.5.0 under java 6 in debug mode.

After last idea update I faced to error specified in subject.

Looks like debugger agent bootstrapped class file compiled under newer java version and cannot be used any more under java 6.

Does exists any workaround in this situation?

Make sure the JAVA_HOME variable in the WebLogic configuration and startup files points to a correct version of Java.

Make sure your project JDK matches that Java version -> 'File | Project Structure' ('Project' and 'Modules' tabs).

Please also provide a demo project where this can be preproduced. You can upload it to https://uploads.jetbrains.com and provide the upload id here.

I just checked this link and got it:  https://blog.jetbrains.com/idea/2022/09/intellij-idea-2022-3-eap/#Java_6_and_older

Anyway I switched to jdk8 in module settings and it seems ok for now.
