Hello Everyone !!!

I was using feel-engine with in worker application to utilize the feel-expressions evaluation.

        <dependency>
            <groupId>org.camunda.feel</groupId>
            <artifactId>feel-engine</artifactId>
            <version>1.16.0</version>
        </dependency>

I was getting below error while running the application. I had upgraded the feel-engine library version from 1.16.0 to 1.19.1 and got below error. Then I downgraded the version from 1.19.1 to 1.16.0, but still getting same error.

JDK version: 17

Caused by: java.lang.UnsupportedClassVersionError: 
io/camunda/zeebe/feel/impl/MessagePackValueMapper has been compiled 
by a more recent version of the Java Runtime (class file version 65.0), 
this version of the Java Runtime only recognizes class file versions up to 61.0

How can we solve this issue without updating the JDK version to 21?

$ java -version
openjdk version “17” 2021-09-14
OpenJDK Runtime Environment (build 17+35-2724)
OpenJDK 64-Bit Server VM (build 17+35-2724, mixed mode, sharing)

$ javac -version
javac 17

Hi @aravindhrs - did a little bit of digging on this with our engineers. feel-scala requires Java 11. However, the MessagePackValueMapper class isn’t part of that package; that is part of Zeebe itself and Zeebe requires JDK 21+.

@nathan.loding Then there’s a fix required for the version-compatibility documentation for 8.6

I have tested with Open JDK v21 and it works fine.

@aravindhrs - I believe that is correct, spring-zeebe requires Java 17+. Zeebe requires 21+.

… what other dependencies do you have in your project?

Hey @aravindhrs - looks like we made a mistake in the spring-zeebe dependencies that unfortunately was missed until your post here! There is a PR open to correct it.

@nathan.loding , Thank you for the support. As a workaround I will be upgrading to JDK 21 until the fix is merged and released.
