Spring Data (2.4+) projection failing while querying LocalDateTime attribute as LocalDate. Same working in SB 2.3.7

[prabhugopal]

We recently upgraded out application to 2.4.5 from 2.3.7, and we facing below exception with spring data (closed) projection.

The projection fails with below exception

Caused by: com.fasterxml.jackson.databind.JsonMappingException: Projection type must be an interface! (through reference chain ***

I went through the following links as it related to this issue, and assuming it is fixed (partially).

#2121

spring-projects/spring-data-commons#2223

https://jira.spring.io/browse/DATACMNS-1836

But it seems the issue still exists, In our situation we have got entities with attributes of type LocalDateTime & the projection attributes with LocalDate. The conversion from LocalDateTime to LocalDate was working without any custom convertor or serializer in SB2.3.7 but after upgrading to SB2.4.5 (tried downgrading to 2.4.0 same issue exists) we get the above exception.
