How the JVM Optimizes Generic Code - A Deep Dive

My #JavaOne talk on "Java and Post-Quantum Cryptography" is now on YouTube. Check it out!

Most companies underestimate vendor risk in their tech stack.
Until it hits them.
Java is different.
Oracle leads and does most of the heavy lifting. IBM, Amazon, Microsoft, SAP, Azul and others all invest in the same platform.
Not a single-vendor story.
That means stability. For companies and for developers.
That’s why I keep recommending Java.
If Java is on your roadmap, let’s talk. At XDEV, we help teams get it right.
(And yes, the Lego Duke from Azul at #JavaOne stays on my desk 😄)

And they say, developer conferences don't have a dress code. Shout out to Volker Simonis for being one of best dressed folks at #JavaOne
Get yourself and an awesome Duke shirt at JCON https://europe.jcon.one

Some of the best people in tech are in the Java community.
Sharat Chander is one of them.
25 years of supporting Java, JUGs, and Java Champions. You can tell he truly cares.
During #JavaOne, he even turned an errand into a great moment. Big US car, country music, good conversation.
That meant a lot.

There’s the Hallway Track… and then there’s the Airport Track.
Chatting with Michal Niczyporuk about planes while watching traffic at SFO. Learning about a great flight tracker: https://globe.adsbexchange.com/
Then a deep dive with Anton Arhipov on license servers, bytecode, and classloaders.
Want in? Wear Java swag. It starts conversations.
If you like that vibe, you’ll enjoy JCON EUROPE:

“Lombok is like cocaine. At first, it feels awesome, but after a while, you regret your choices.”
Heard that at JavaOne last year—and it came back to me today during the fireside chat with Brian Goetz, Ron Pressler & team.
Lombok solved real problems—but by stepping outside the language.
Now Java evolves (records, pattern matching…), and those gaps are closing.
Rely less on workarounds, more on the platform itself. #JavaOne

Day 2 at JavaOne: one theme stood out.
Java keeps getting faster… without us changing much.
The JIT improvements from 21 → 26 alone are significant (Netflix saw up to 3.5x in cases). Not one big change—constant small ones that compound.
Brian Goetz said: “Thinking is hard.”
Feels true.
Code gets easier. Performance gets “free.” Thinking is the work.Before you optimize—try Java 26 and measure.
