Vaadin 25: JsonValue[] argument is not instrumented #23

Description

@javier-godoy

Describe the bug

Caused by: tools.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of elemental.json.JsonValue (no Creators, like default constructor, exist): abstract types either need to be mapped to concrete types, have custom deserializer, or contain additional type information

Expected behavior

A JsonValue[] argument must be instrumented as JsonNode[]
