On a copied installation of Jenkins 1.609 to a new server, I notice that when I select a build and click "configure", I get a greyed-out config page with "LOADING" as a watermark that never goes away. At the same time I see in catalina.out lots of errors such as this:
Jul 12, 2021 4:15:20 PM hudson.ExpressionFactory2$JexlExpression evaluate WARNING: Caught exception evaluating: d.helpFile in /jenkins/job/platform%20set%20branch%20name/configure. Reason: jav a.lang.reflect.InvocationTargetException .... .... Caused by: java.lang.UnsupportedClassVersionError: org/jenkinsci/plugins/scriptsecurity/sandbox/RejectedAccessException : Unsupported major.minor version 52.0 I think the reason is that, for a few days, I was running the new Jenkins with a slightly newer Java version (1.6.0_41 rather than 1.6.0_30). Now I have made sure I run it with _30. During this short period this particular build has been executed a few times. However I do get the same problem on other builds that have not executed on this new server. Almost all errors (or warnings if you will) are about the script-security plugin. Please advise. - George -- You received this message because you are subscribed to the Google Groups "Jenkins Users" group.
