EclipseCon conference is a great event for all Java developers, especially those who are passionate about and believe in opensource. The conference is scheduled for 26-28 October 2021. I wholeheartedly recommend to attend it. It’s a free online event, you just need to register to attend: https://www.eclipsecon.org/2021
Specifically for users of Jakarta EE it might be even more interesting to attend the Jakarta EE Community Day, which happens the day before the main conference on 25 October 2021. It’s open to all people that register for the main EclipseCon event. There’s a packed agenda centered on the Jakarta EE, MicroProfile and Cloud Native Java communities, including topics like the present and future of MicroProfile and Jakarta EE, and upcoming features in Jakarta Security, Jakarta Concurrency, Jakarta REST, and Jakarta NoSQL.
If you’re interested, I recommend reading an article of Reza Rahman about what’s happening at the Community Day and why to attend it. Or simply go ahead and register for EclipseCon 2021!
