JavaLand 2026 was finally back in the theme park after the last two year’s disaster at a car racing track. And this was good. Europa Park is different from Phantasialand, but has the same kitchy, German way of going all in being true to the theme. From the African and...
I can’t believe this was the ninth time I was a speaker at Devnexus. The last couple of years, we have sponsored and had a dedicated Jakarta EE track and the entire team present, so it was a bit different to be handling the booth as the only one from...
A lot has been written about AI in software development. Much of it focuses on what the technology can do, or what teams have already built with it. What is discussed less often is how teams responsible for widely used systems can introduce these tools carefully. This post looks at...
Welcome to issue number three hundred and twenty-three of Hashtag Jakarta EE! Right now, I am on my way home from Devnexus 2026. It was as busy as always, so I haven’t been able to finish up my post from the event, but I promise that it will be out...
Many of the most influential open source projects begin in academic environments. Universities and higher education institutions are well suited to experimentation and have been central to open source for decades.

Many discussions about open source AI agents start with the same image: a single assistant responding to prompts. That model works well for demonstrations, but it breaks down quickly in production. One of our speakers for the AI track at OCX 26, Luca Bianchi, explained in an interview, “a production...
Welcome to issue number three hundred and twenty-two of Hashtag Jakarta EE! This week, I was in Montreal for ConFoo. The conference season is over us, and already next week, I will be in Atlanta for Devnexus. At Devnexus, I will be managing the Jakarta EE booth in addition to...
This was my fifth time speaking at ConFoo in Montreal. This year, there were around 800 attendees, which brings them close to the peak years before the pandemic. I am happy to see and experience the vibrant developer community in Montreal. The conference was originally a PHP conference, but now...
For decades, Java has drawn a clear distinction between primitive types and reference types, with each category following its own rules in the language. One of those rules was simple: instanceof applies to reference types, not primitives. That separation has shaped how generations of Java developers reason about type checks...
With the exception of channels created to discuss security issues while they are in quarantine (and closed channels reserved for working group committee discussions), we provide no private channels for open source projects. This means that we do not provide private mailing lists (or any other private channels) for any...
