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
