      I'm using Jenkins 2.462.1 LTS with Java 11 IBM Semeru, it was working fine with Java 11 but when i'm trying to upgrade Java 11 to 17, Jenkins is broken due to below error on startup 

      java.lang.NullPointerException: Cannot invoke "java.lang.Object.getClass()" because "s" is null at java.base/java.util.Collections.unmodifiableSet(Collections.java:1132) at PluginClassLoader for scriptler//org.jenkinsci.plugins.scriptler.config.ScriptSet.getScripts(ScriptSet.java:80) at PluginClassLoader for scriptler//org.jenkinsci.plugins.scriptler.config.ScriptlerConfiguration.load(ScriptlerConfiguration.java:105) at PluginClassLoader for scriptler//org.jenkinsci.plugins.scriptler.ScriptlerLoadingTasks.synchronizeConfig(ScriptlerLoadingTasks.java:65) Caused: java.lang.reflect.InvocationTargetException at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:77) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:575) at hudson.init.TaskMethodFinder.invoke(TaskMethodFinder.java:109) Caused: java.lang.Error at hudson.init.TaskMethodFinder.invoke(TaskMethodFinder.java:115) at hudson.init.TaskMethodFinder$TaskImpl.run(TaskMethodFinder.java:185) at org.jvnet.hudson.reactor.Reactor.runTask(Reactor.java:305) at jenkins.model.Jenkins$5.runTask(Jenkins.java:1175) at org.jvnet.hudson.reactor.Reactor$2.run(Reactor.java:221) at org.jvnet.hudson.reactor.Reactor$Node.run(Reactor.java:120) at jenkins.security.ImpersonatingExecutorService$1.run(ImpersonatingExecutorService.java:68) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1136) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:635) at java.base/java.lang.Thread.run(Thread.java:857) Caused: org.jvnet.hudson.reactor.ReactorException at org.jvnet.hudson.reactor.Reactor.execute(Reactor.java:290) at jenkins.InitReactorRunner.run(InitReactorRunner.java:49) at jenkins.model.Jenkins.executeReactor(Jenkins.java:1210) at jenkins.model.Jenkins.<init>(Jenkins.java:997) at hudson.model.Hudson.<init>(Hudson.java:86) at hudson.model.Hudson.<init>(Hudson.java:82) at hudson.WebAppMain$3.run(WebAppMain.java:248) Caused: hudson.util.HudsonFailedToLoad at hudson.WebAppMain$3.run(WebAppMain.java:273)

      It looks like there is some issue with Scriptler plugin. Could you please have a look and let me root cause of the issue ?

       

      More details:

      OS - RHEL 8.6

      Java - IBM Semeru Runtime Open Edition 17.0.12.1

      Jenkins - 2.462.1 LTS

          IBM Semeru is the OpenJ9 JDK. Jenkins stopped testing the Semeru Java versions a year or two ago. The Java support policy says:

          Jenkins maintainers actively test HotSpot based Java virtual machines like those from OpenJDK, Eclipse Temurin, and Amazon Corretto. Jenkins maintainers do not test Eclipse OpenJ9 based Java virtual machines. The Platform Special Interest Group does not actively work on OpenJ9 based Java virtual machines.

          Switch to a HotSpot JVM.

          Thank you markewaite for recommendation, i have changed JVM from IBM Semeru OpenJ9 JDK to Eclipse Temurin-17.0.12+7, but still same below error persists on startup. Any idea what's going wrong with Jenkins ?

          Can you duplicate that failure on a fresh installation?

          If not, what is difference between your installation and a fresh install?

          Can you provide details as described in "How to report an issue" so that others have a better chance of duplicating your configuration?
