[JENKINS-35352] unclassified field org.jenkinsci.plugins.workflow.support.steps.build.RunWrapper result when trying to call setResult on wrong type

I'm not sure if this can be consider a bug but all the information I found using the exception name refers to classes not supported in the sandbox that should be so this case could be the another case.

I did not find a way to allow this
