Why

Same as the issue raised in https://jira.mongodb.org/browse/JAVA-5134, this change implements a mechanism to gracefully handle stored nulls for fields that are annotated with JSR305 @Nullable annotations.

Changes

  • Introduce a boolean field isNullable to RecordCodec.ComponentModel, which is set to true when given field is not primitive.
  • When decoding stored null for a field that is considered nullable in above step, read null in stead of throwing an BsonInvalidOperationException.
  • For any other scenarios, previous codec behaviour is preserved.
