I had a great time speaking at the Philly JUG Yesterday! The topic of my talk was the implications of the namespace change from javax.* to jakarta.* in Jakarta EE 9 when migrating from Spring Boot 2 to Spring Boot 3. The slides are available on SpeakerDeck.

Before the event, I had the opportunity to explore Philadelphia. It is an interesting city to visit with a lot of American history. For those of us who grew up in the 80s, a selfie with the statue of Rocky is a must. It is kind of funny to see that it is just as popular with the younger generation as well. Groups of teenagers blast Eye of the Tiger from their phones while running up the iconic “Rocky steps” and taking pictures of the statue even if they weren’t even born when the movie came out..

I also checked out the Liberty Bell, which you could argue is a bit more historically significant than a move about a boxer, but who am I to say? For lunch, I had a Philly Cheesesteak. So simple, but still so good…
