Yes, that seems wrong.

Unfortunately I can not reproduce this against 2.9.2. But I vaguely remember something like this, which was due to refactoring of type id handling in 2.9. So one thing to check is to make 100% sure that dependencies for jackson-core (especially) and jackson-databind are 2.9.2 and not, say, 2.9.0.
(jackson-annotations is fine to be 2.9.0 -- this jar never changes in patches).

I made a test project for it https://github.com/unintended/localdatetest
All the dependencies are 2.9.2, but it still fails:

The strange thing is that in console log it's logged as double and triple brackets:
testLocalDateSerialization(com.jackson.test.ObjectMapperTest) Time elapsed: 0.299 sec <<< FAILURE!
org.junit.ComparisonFailure: expected:<...va.time.LocalDate":[[2017,12,5]]}}> but was:<...va.time.LocalDate":[[[2017,12,5]]]}}>
In IDEA still:
org.junit.ComparisonFailure:
Expected :{"localDate":[2017,12,5],"object":{"java.time.LocalDate":[2017,12,5]}}
Actual :{"localDate":[2017,12,5],"object":{"java.time.LocalDate":[[2017,12,5]]}}

2.8.10 works well btw

Hmmh. Well that is odd. Will try to see if I can reproduce it locally then.
As I said, problem itself does sound familiar, I just do not remember where. Another thing that is different is inclusion of parameter names module, but I don't think that should matter here.

It’s just a copy-paste from my main project, so I forgot to remove parameter module from dependencies, but during experiments I tried to remove it, and it didn’t make any difference.

Oh lol. My test failed to fail because it wasn't being run. Once that is resolved it fails as expected.
And I think I can see why now; it is not overriding default polymorphic type handling from base implementation, which assumers scalar representation.
