java.lang.ClassCastException: class lucee.runtime.java.JavaObject cannot be cast to class io.proactive.GraphQLProvider

Description

Hi,
I’m getting casting errors in multiple places as we try to upgrade from lucee 5 to 6
The following works in 6.1.1.118 but breaks in 6.2.0.284 (but we can’t use 6.1.1.118 because of other issues)
we are getting casting errors when passing Lucee objects to Java. Below is one example

//Application.cfc code creating our custom WebSocketServer for GraphQL subscriptions ... application.GQL = new GraphQL() var websocketServer = createObject("java", "websockets.WebSocketServer").init(application.GQL)

 

//GraphQL.cfc component displayname="GraphQL" { this.GQL = createObject("java","path.to.GraphQLProvider") public any function init() { ...
//WebSocketServer.java public WebSocketServer(Component graphqlObject) { //trying to cast graphqlObject passed from cf to type GraphQLProvider GraphQLProvider context = (GraphQLProvider) graphqlObject.get("GQL"); }

This Works in 5.4.3.16-light-nginx-tomcat9.0-jdk11-temurin-focal or lucee:6.1.1.118-nginx-tomcat9.0-jdk21-temurin-jammy

In 6.2.0.284 we get this error

java.lang.ClassCastException: class lucee.runtime.java.JavaObject cannot be cast to class io.proactive.GraphQLProvider (lucee.runtime.java.JavaObject is in unnamed module of loader org.apache.felix.framework.BundleWiringImpl$BundleClassLoader @205b132e; io.proactive.GraphQLProvider is in unnamed module of loader java.net.URLClassLoader @1cf4f579) graphql-app | at websockets.WebSocketServer.<init>(WebSocketServer.java:26) graphql-app | at lucee.invoc.wrap.v4.websockets.WebSocketServer.____init_____11gjzcmqfqnlx.apply(Unknown Source) graphql-app | at lucee.runtime.reflection.pairs.ConstructorInstance.invoke(ConstructorInstance.java:63) graphql-app | at lucee.runtime.reflection.Reflector.callConstructor(Reflector.java:841) graphql-app | at lucee.runtime.java.JavaObject.init(JavaObject.java:308) graphql-app | at lucee.runtime.java.JavaObject.call(JavaObject.java:247) graphql-app | at lucee.runtime.java.JavaObject.call(JavaObject.java:280) graphql-app | at lucee.runtime.util.VariableUtilImpl.callFunctionWithoutNamedValues(VariableUtilImpl.java:797) graphql-app | at lucee.runtime.PageContextImpl.getFunction(PageContextImpl.java:2050) graphql-app | at application_cfc$cf.udfCall(/Application.cfc:120)

Please let me know if you need any further info.
