Additional context

What is "WAS Liberty App Server"? Does it have some connection to JBoss/WildFly?

[ram3shpala]

WebSphere Liberty is MicroProfile application server from IBM. For more info https://www.ibm.com/in-en/cloud/websphere-liberty

[thurka]

The error looks very similar to JBoss/WildFly. JBoss has to be started with "-Djboss.modules.system.pkgs=org.jboss.byteman,org.graalvm.visualvm.lib.jfluid.server" system property to allow loading of profiler classes from org.graalvm.visualvm.lib.jfluid.server package. Maybe something similar can be done for WebSphere Liberty because it also uses OSGI framerowk with boot delegation.

Thanks for update. Appreciate quick response.
Added -Dorg.osgi.framework.bootdelegation=org.graalvm.* to Liberty Server its working now.

The only way this -Dorg.osgi.framework.bootdelegation=org.graalvm.* worked is by added this to my bootstrap.properties. It did not work when I made this a JVM arg when running the jar or adding it to my jvm.options file

I got the same error but with wildfly

To be precise, adding the following to bootstrap.properties works for OpenLiberty.

org.osgi.framework.bootdelegation=org.graalvm.*
