Projection instances can't be serialized [DATACMNS-1160]

Varun Mehta opened DATACMNS-1160 and commented

When using Projections in conjunction with @Query and redis cache, redis JdkSerializationRedisSerializer is unable to serialize the data and store it in redis cache.

Sample project with test case is available here; https://github.com/varunmehta/spring-cache-error
