Hello,
We recently updated our camunda-bpm-spring-boot-starter to 7.17.0 in order to update to java 17.
The camunda update went well but when we migrated to java 17, a java.lang.reflect.InaccessibleObjectException appeared in our bpmn unit tests.
However, we don’t see this exception when running the application.
I know there is a workaround consisting in changing the jvm args on the unit tests execution to open the java.util module but I’d like a more durable resolution of my issue. I don’t feel confident running my application in production with the jvm customized for my unit tests.
Could anyone help me with this issue ?
Thanks
