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.
