This Map serializer is implemented in terms of the Java version and is somewhat fragile, as discussed in FasterXML#643 / FasterXML#470. This commit ensures that the wrapper class is a member class in both Scala and Java. That results in this JSON as the serializer code chooses not to put the inner class name in the type annotation. ``` {"m":["scala.collection.immutable.Map",{"one":"one","two":"two"}]} ``` Fixes FasterXML#643

Thanks @retronym - I think this is safe to include in the 2.16.1 release, so I've backported it back to the 2.16 branch. I'm surprised that the core jackson-databind writes the pre-conversion class name with this change but it obviously works based on your test case. The test case should help us spot if the core jackson-databind library modifies this behaviour. |
