1.Overview

We need to upgrade our Platform Core libraries ,to be able to leaverage all the latest functionalities in the latest released versions of these libraries. As first priority we would need to upgrade Java . This project will address the issues that will arise during the Upgrade.

2.Objectives

Main Objectives

Upgrading Java from OpenJDK 8 to OpenJDK 11. Note that Java 11 is Only supported out of the box in Spring 5. (COMPLETED)

Extra Credit

  • Upgrading other Libraries that are pending.

3.GSoC Contributions

I did work on FHIR module and FHIR Module v2 Since we are replacing the FHIR module module with FHIR Module v2 and FHIR Module v2 is still in the development .

6.Future Works:

  1. migrating to using JPA instead of raw Hibernate. The rationale for this is less to enable supporting other JPA providers and more because Hibernate’s new feature development is primarily focused on being a proper implementation of the JPA spec. So, for example JQL gets more attention than HQL these days and the Hibernate Criteria API has been “deprecated” in favour of the JPA version (it’s not going away anytime soon; it’s just not receiving new features).

  2. Migrate to using a child Spring context per module instead of a single big Spring context. This is much more pie-in-the-sky, but it could likely result in a reduction of the time it takes to refresh the main Spring context (which is a large chunk of the start-up time). This would need to be tested to ensure that, e.g., modules can still add services to the Context object, etc.

7.Thoughts on GSoC:

It has been a wonderful experience for me for the last 12 weeks to work with OpenMRS and GSoC community. I would like to thank the entire OpenMRS community for providing me with this opportunity, my mentors Moses Mutesasira and Sharif Magembe, Ivo Ulrich, Daniel Kayiwa, Ian Bacher for the support and help they gave me through out the process and at last Google for this wonderful experience .
