Hi Daniel, thanks for looking into this and sorry to reopen this. I know that remoting does not support the older JDKs, so does the maven build job type. For that reason the JDK switch was implemented which works fine on a local build Retrying with slave Java and setting compile/test properties to point to /export/sbs/jenkins/home/tools/hudson.model.JDK/JDK_1.6.0_latest_., but fails on the remote build. I assume it is because of a different exception raised in this case with the new remoting, but I'm do not have deep knowledge here. Something like Jesse Glick did in the linked ticket https://issues.jenkins-ci.org/browse/JENKINS-25272?focusedCommentId=234013&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-234013 might fix the issue described here. Kind Regards, Andreas.

Re: Jenkins 2.32.1 causes Java 5/6 Maven builds to fail My apologies for closing. I saw the Maven output and came to the wrong conclusion. Looks like a Maven Plugin issue then.

Re: Jenkins 2.32.1 causes Java 5/6 Maven builds to fail Ok, cause is that with the new remoting} the causing {{UnsupportedClassVersionError is not part of the getCause chain of the caught IOException any more. Need to find out how the cause is reported now through the channel.
