Description
java.lang.RuntimeException: Hello should be in the classlist
	at PatchModuleClassList.main(PatchModuleClassList.java:142)
	at java.base/jdk.internal.reflect.DirectMethodHandleAccessor.invoke(DirectMethodHandleAccessor.java:104)
	at java.base/java.lang.reflect.Method.invoke(Method.java:565)
	at com.sun.javatest.regtest.agent.MainActionHelper$AgentVMRunnable.run(MainActionHelper.java:335)
	at java.base/java.lang.Thread.run(Thread.java:1474)

This corresponds to scenario 3. I've attached the two classlist outputs, without and with --enable-preview, respectively. 

Problemlisting for now.
Comments
Pretty sure this is caused by heap dumping being disabled. Will re-open if this is not fixed when CDS heap dumping is enabled.

I'm unable to reproduce this locally with the CDS draft.
