• MicroProfile was created basically to extend the Enterprise Java environment for developing microservices and make entreprise Java cloud ready! That was before Oracle donated the Java EE project under EE4J than the new brand name Jakarta EE. Both project are lead by the Eclipse Foundation and have mainly the same player. This session was to discuss about the future of Entreprise Java development in general and  why not these two forces combine for a better future

Design Patterns have strongly influenced the way that Java was coded. By studying them, we can improve our understanding of the various libraries of the JDK. This discussion had thoughts from different perspectives. On the one camp were those that thought patterns did not matter, but in most cases, it was the misapplication of patterns that was at fault. In the other camps were those that had noticed a positive effect in their teams once good design was studied. We also talk about study groups and how they can assist in helping the comprehension of patterns within a team.

n this session we analyzed advances and novel techniques regarding cloud-deployed JVMs.

On one hand, we discussed how current JVMs can be extended in order to exploit the heterogeneous hardware accelerators commonly found on cloud deployments such as GPUs and FPGAs.

Challenges in JIT compilation, memory management and programming models as well as upcoming solutions such as the TornadoVM were discussed.

Orthogonally to the aforementioned discussion topics, advances in providing lightweight AOT compiled JVMs were also discussed.

• We have been building API based software for years, but the work of managing those APIs is still a big challenge. Moreover now we are leaving in a word where the Cloud-native architectures are currently on everyone's lips. and of course cloud-native without APIs does not make sense! Right? How does the topic API Management fit into this new world?How should an API be designed, built and implemented? monitored? secured? What needs to change when the number of APIs grows?
• In this session we had also a discussion about building Java API, not REST APIs, including the implications of breaking compatibility, creating excellent documentation, etc
