Deserialization/Instantiation failures at rest endpoint with multi-level generics

[ChrisSchoe]

Describe the bug

Using Quarkus 2.0.1 with resteasy and jsonb fails in some cases when using classes for request bodies whose definition relies on multiple levels of generics. A minimal example can be found here.
When using Quarkus 1.13 everything works fine.

Expected behavior

Sending a POST request with the suitable json body to the hello endpoint should return status Code 200 and the text "Hello RestEasyNAME", where NAME is the name given in the json body, e.g.
curl -X 'POST' \ 'http://localhost:8080/hello' \ -H 'accept: text/plain' \ -H 'Content-Type: application/json' \ -d '{ "child": { "name": "string", "nickname": "Quarkus" } }'
should result in Hello RESTEasyQuarkus.

Actual behavior

We get a classloader error, as it is attempted to initialise the child field of the ConcreteContainer object by an object of type AbstractChild, which leads to the following error:

ERROR [io.qua.ver.htt.run.QuarkusErrorHandler] (executor-thread-0) HTTP Request to /hello failed, error id: 576852dd-c3db-4714-b956-7c776b83fe00-1: org.jboss.resteasy.spi.UnhandledException: java.lang.ClassCastException: class model.AbstractChild cannot be cast to class model.ConcreteChild (model.AbstractChild and model.ConcreteChild are in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @3256951b) at org.jboss.resteasy.core.ExceptionHandler.handleApplicationException(ExceptionHandler.java:106) at org.jboss.resteasy.core.ExceptionHandler.handleException(ExceptionHandler.java:372) at org.jboss.resteasy.core.SynchronousDispatcher.writeException(SynchronousDispatcher.java:218) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:519) at org.jboss.resteasy.core.SynchronousDispatcher.lambda$invoke$4(SynchronousDispatcher.java:261) at org.jboss.resteasy.core.SynchronousDispatcher.lambda$preprocess$0(SynchronousDispatcher.java:161) at org.jboss.resteasy.core.interception.jaxrs.PreMatchContainerRequestContext.filter(PreMatchContainerRequestContext.java:364) at org.jboss.resteasy.core.SynchronousDispatcher.preprocess(SynchronousDispatcher.java:164) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:247) at io.quarkus.resteasy.runtime.standalone.RequestDispatcher.service(RequestDispatcher.java:73) at io.quarkus.resteasy.runtime.standalone.VertxRequestHandler.dispatch(VertxRequestHandler.java:138) at io.quarkus.resteasy.runtime.standalone.VertxRequestHandler$1.run(VertxRequestHandler.java:93) at io.quarkus.vertx.core.runtime.VertxCoreRecorder$14.runWith(VertxCoreRecorder.java:481) at org.jboss.threads.EnhancedQueueExecutor$Task.run(EnhancedQueueExecutor.java:2442) at org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1476) at org.jboss.threads.DelegatingRunnable.run(DelegatingRunnable.java:29) at org.jboss.threads.ThreadLocalResettingRunnable.run(ThreadLocalResettingRunnable.java:29) at io.netty.util.concurrent.FastThreadLocalRunnable.run(FastThreadLocalRunnable.java:30) at java.base/java.lang.Thread.run(Thread.java:834) Caused by: java.lang.ClassCastException: class model.AbstractChild cannot be cast to class model.ConcreteChild (model.AbstractChild and model.ConcreteChild are in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @3256951b) at org.acme.getting.started.GreetingResource.hello(GreetingResource.java:18) at org.acme.getting.started.GreetingResource_Subclass.hello$$superforward1(GreetingResource_Subclass.zig:94) at org.acme.getting.started.GreetingResource_Subclass$$function$$2.apply(GreetingResource_Subclass$$function$$2.zig:33) at io.quarkus.arc.impl.AroundInvokeInvocationContext.proceed(AroundInvokeInvocationContext.java:54) at io.quarkus.arc.runtime.devconsole.InvocationInterceptor.proceed(InvocationInterceptor.java:62) at io.quarkus.arc.runtime.devconsole.InvocationInterceptor.monitor(InvocationInterceptor.java:49) at io.quarkus.arc.runtime.devconsole.InvocationInterceptor_Bean.intercept(InvocationInterceptor_Bean.zig:521) at io.quarkus.arc.impl.InterceptorInvocation.invoke(InterceptorInvocation.java:41) at io.quarkus.arc.impl.AroundInvokeInvocationContext.perform(AroundInvokeInvocationContext.java:41) at io.quarkus.arc.impl.InvocationContexts.performAroundInvoke(InvocationContexts.java:32) at org.acme.getting.started.GreetingResource_Subclass.hello(GreetingResource_Subclass.zig:158) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:170) at org.jboss.resteasy.core.MethodInjectorImpl.invoke(MethodInjectorImpl.java:130) at org.jboss.resteasy.core.ResourceMethodInvoker.internalInvokeOnTarget(ResourceMethodInvoker.java:660) at org.jboss.resteasy.core.ResourceMethodInvoker.invokeOnTargetAfterFilter(ResourceMethodInvoker.java:524) at org.jboss.resteasy.core.ResourceMethodInvoker.lambda$invokeOnTarget$2(ResourceMethodInvoker.java:474) at org.jboss.resteasy.core.interception.jaxrs.PreMatchContainerRequestContext.filter(PreMatchContainerRequestContext.java:364) at org.jboss.resteasy.core.ResourceMethodInvoker.invokeOnTarget(ResourceMethodInvoker.java:476) at org.jboss.resteasy.core.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:434) at org.jboss.resteasy.core.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:408) at org.jboss.resteasy.core.ResourceMethodInvoker.invoke(ResourceMethodInvoker.java:69) at org.jboss.resteasy.core.SynchronousDispatcher.invoke(SynchronousDispatcher.java:492) ... 15 more

How to Reproduce?

cf. GitHub repo.

The branch 'workaround' contains a minor change that at least provides working code. However, this should not be necessary.

This is related to the upgrade from Yasson 1.0.8 to 1.0.9, if you force version 1.0.8 this works.

Can you report it at the Yasson project: https://github.com/eclipse-ee4j/yasson

Closing as we now seem to be including a Yasson version that fixes the issue
