Imports

java.io.IOException, java.util.*, .Map.Entry, com.fasterxml.jackson.annotation.ObjectIdGenerator, .ObjectIdResolver, .ObjectIdGenerator.IdKey, com.fasterxml.jackson.core.JsonParser, .JsonToken, com.fasterxml.jackson.databind.*, com.fasterxml.jackson.databind.cfg.CacheProvider, .HandlerInstantiator, com.fasterxml.jackson.databind.deser.impl.ReadableObjectId, .ReadableObjectId.Referring, com.fasterxml.jackson.databind.introspect.Annotated, com.fasterxml.jackson.databind.util.ClassUtil

Complete DeserializationContext implementation that adds extended API for ObjectMapper (and ObjectReader) to call, as well as implements certain parts that base class has left abstract. The remaining abstract methods (createInstance, with) are left so that custom implementations will properly implement them to return intended subtype.
