Start in wayang-api/wayang-api-scala-java/src/main/scala/org/apache/wayang/api/serialization/customserializers/PlatformDeserializer.scala at the TODO and inspect the platform implementations available in the repository. Determine which platform class names must be accepted and verify that each can be deserialized without triggering the existing WayangException.
