Spring I/O 2025 was a great experience! It is an extremely well-organized conference with an awesome community. It was my second time as a speaker, and I will definitely send talk abstracts to the upcoming editions as well. It does not hurt that it is organized in Barcelona in May. A very nice time of the year to visit the city.

My session, What Every Spring Developer Should Know About Jakarta EE, went well. I created a couple of brand new live coding demos for this talk, which is always a bit shaky the first time. But I think I pulled if off. I admit that I cheated a little bit in the last demo to be able to get it to run…
But I was able to fix it the next day, so the code in the GitHub repository behaves correctly.

One of the great things of Spring I/O is the speaker trip on the day after the conference. A bus full of speakers were bussed out in the wine country where we went for a bike ride among the vineyards. We could choose between electric tour cycles, or proper road cycles. Those of us that chose the road bikes got a beautiful Spring I/O cycling jersey.
