Thank you @njr-11 @pmd1nh @pnicolucci for your review! I think I have addressed all of your comments. Please double check

In the future, if the code suggestions are acceptable, just accept them to be applied directly to the PR instead of retyping them. The latter is both error prone and causes extra review time for the code reviewer. (An accepted suggestion doesn't need to be re-reviewed because you know what you suggested before was applied exactly, whereas as with re-typed updates, the reviewer needs to spend time figuring out if the suggestion was applied at all and whether it might differ in some way that introduces errors or typos)

Suggested change

return executorService.supplyAsync(this::processData);;

return executorService.supplyAsync(this::processData);

Reopening because this was marked resolved without actually changing it.

normally I would... I tried to keep the number of commits low for easier to re-review and use my local version as the master copy. Thank you @njr-11 for spending time to re-review this!

That did not make it easier to review. It made it harder, took longer for the reviewer, and introduced mistakes. If your goal is to reduce commits, use the "Add suggestion to batch" for suggested changes, which puts all of them into a single commit.

+Jakarta RESTful Web Services 4.0 provides a foundational API to develop web services following the Representational State Transfer (REST) architectural pattern. The goal of this release is to remove the JAXB dependency and ManagedBean support from Jakarta RESTful Web Services and add TCK tests to fill verification gaps while maintaining backward compatibility with earlier releases.


Kindly update the summary to include the new features also.

Jakarta RESTful Web Services 4.0 provides a foundational API to develop web services following the Representational State Transfer (REST) architectural pattern. New features include a convenience method for checking header value lists to easily verify whether a header contains specific values, the addition of a method to retrieve the matched resource template, and support for RFC 7396 JSON Merge Patch operations. The release also aims to remove the JAXB dependency and ManagedBean support from Jakarta RESTful Web Services and add TCK tests to fill verification gaps while maintaining backward compatibility with earlier releases.

I debate including the full spelling out of CDI as well. Also it isn't quite a full list. Annotations 3.0 and Interceptors 2.2 are not included. I think it is important to show @ManagedBean annotation being removed and how a user would need to transition to using @Inject to replace its usage.

+- *Query Methods*: Adds `getSingleResultOrNull()` to `Query`, `TypedQuery`, `StoredProcedureQuery`

You missed the Deprecations in Persistence 3.2 , Could you please update

`Deprecations in Persistence 3.2:

Legacy Date/Time API Deprecation: Deprecates usage of Calendar, Date, Time, Timestamp, @Temporal, @MapKeyTemporal, and TemporalType in new applications in favor of the java.time API. Applications are encouraged to migrate to LocalDate, LocalDateTime, Instant, and other java.time types.

Criteria API Deprecation: Deprecates multiselect() methods in CriteriaQuery. Applications should use array() or tuple() methods provided by CriteriaBuilder.

Wrapper Array Type Deprecation: Deprecates Byte[] and Character[] array types for basic attributes in favor of primitive arrays (byte[] and char[]).

Deprecations for Future Removal:

Graph API Deprecations:
- Deprecates addSubclassSubgraph() in EntityGraph for future removal; addTreatedSubgraph() should be used instead.
- Deprecates addSubgraph(Attribute, Class) and addKeySubgraph() in Graph, EntityGraph, and Subgraph for future removal; addTreatedSubgraph(Attribute, Class) and addMapKeySubgraph() should be used instead.

Transaction Type Deprecation: Deprecates jakarta.persistence.spi.PersistenceUnitTransactionType for future removal; applications should use jakarta.persistence.PersistenceUnitTransactionType instead.

Persistence Class Deprecations: Deprecates the default public no-arg constructor in jakarta.persistence.Persistence, along with the PERSISTENCE_PROVIDER and providers fields, for future removal with no replacement. The class is not intended for extensibility.`

+- *Null Precedence*: Adds support for specifying null precedence when ordering Jakarta Persistence QL and criteria queries
+- *Query Methods*: Adds `getSingleResultOrNull()` to `Query`, `TypedQuery`, `StoredProcedureQuery`
+- *Named Queries*: Adds `entities()`, `classes()` and `columns()` to `NamedNativeQuery`
+- *Lock Mode*: Adds `lockMode()` to `EntityResult` with the default being `OPTIMISTIC`


please add the missing new features.

Transaction Helpers: Adds runInTransaction() and callInTransaction() convenience methods

EntityManager Connection Access: Adds runWithConnection() and callWithConnection() methods for JDBC connection access

Programmatic Configuration API: Adds PersistenceConfiguration for programmatic persistence unit configuration

Schema Management API: Adds SchemaManager for schema creation, validation, truncation, and dropping
