Hi!
I am currently migrating a project from Ktor-1.6.8/Kotlin-1.6.10 to Ktor-2.0.0/Kotlin-1.6.20 and something has changed with the ClassLoader-behavior: I cannot cast a received object from the (Apache-ActiveMQ-Artemis-)message-queue to the corresponding DTO anymore. In Ktor-1.6.8 an "OverridingClassLoader" was being used while in Ktor-2.0.0 it is "ClassLoader@AppClassLoader". How can I fix this to get rid of the ClassCastException?
