Unecesarry final in BeanDeserializerBase causing production problems for custom deserializers

[Ghoughpteighbteau]

public final Object deserializeWithType(JsonParser jp, DeserializationContext ctxt,
            TypeDeserializer typeDeserializer)

is the only entry point for when jackson mapper is deserializing a collection of objects with polymorphic types.

I have a custom version of the beanDeserializer that does partial updates, it also pulls references from our database when we use syntax that indicates a reference.

However because this field is marked as final, I can't change the deserialization behaviour for references inside collection if the types are polymorphic.

I have being trying to work around this problem for a month. a literal month.

please remove this keyword!

Which version is this?

[Ghoughpteighbteau]

well. I'm using version 2.2.0

but it's in this version as well. Here:

jackson-databind/src/main/java/com/fasterxml/jackson/databind/deser/BeanDeserializerBase.java

Line 919 in 72ce52f

Fix for 2.3 branch (for 2.3.3 if and when it is released), master (for 2.4.0).

Earlier branches are not maintained so new version of 2.1 or 2.2 will be released.

[Ghoughpteighbteau]

That's more than enough! Thanks Tatu! I'll just jump to 2.3 with the fix.

I should of asked for that sooner rather than try and hack around it. I am perhaps too cynical 😊

:)

No problem. I wish I had gotten this in 2.3.2, but better late than never.
