The Payara Monthly Catch: May 2022

We provide our selection of the best Java and Jakarta EE tutorials, videos, podcasts, blogs and news from the month of May! We also pick the best content we've found from the worlds of DevOps, cloud computing and open source. This is a carefully curated reading list, specially selected for our specific Enterprise Java niche. 

This month, we headed toDevoxx UK in London, one of Team Payara's first in-person conferences in a while! It was a great opportunity to connect with those who useJakarta EE(and Payara!) face-to-face, find out what is engaging and bothering our users - and learn more about the industry. Find our pick of the most relevant talks in this roundup. We'll also be atJNationin Portugal on June 7, so please do say hello if you see us there.

It is an exciting time for our community, as the coming month, June 2022, will see the launch ofJakarta EE 10. Project Loom JEP is also targeted for Open JDK 19, bringing much anticipated virtual threading. We've collated some informative articles on this below.

TheNew RelicState of Java ecosystem report also came out this month, revealing the growth of Azuland EclipseAdoptiumin theOpenJDKDistribution Market. We also include lots of other OpenJDK, Azul and Eclipse content below - supporting innovation as the Java and Jakarta EE universe continues to evolve and expand!

Remember: with Jakarta EE 10, Payara Community will no longer be supporting Jakarta EE 8, so plan ahead - will you move to Jakarta EE 10 with Payara Community or choose to invest in Enterprise? Find out morehere.
