OpenJDK Interim Policy on Generative AI

https://openjdk.org/legal/ai

#OpenJDK #Java

So, #Microsoft says Co-Pilot is a tool for entertainment and the other #AI company nobody talks about sounds like this

> Generative AI tools, by their nature, make it easy to create large quantities of plausible-looking code, with plausible-looking tests, which is nonetheless incorrect or, even if it is correct, is poorly designed and therefore difficult to maintain.

This is from #Oracle in there “OpenJDK Interim Policy on Generative AI”

I'll be doing some of the work on my live coding stream on Fridays, starting April 10th at 12pm PDT (7pm UTC). That'll be a short, 1-hour stream, due to other commitments. Future streams will be ~3 hours and you'll be able to AMA on #Java, #Spring, etc.

@xilerk Good catch! This command did the trick:

$ mvn -D versions.outputLineWidth=${COLUMNS} versions:display-dependency-updates

Of course, ${COLUMS} could be set to some arbitrary huge value to help better ensure single line per dependency.

Thanks a bunch for the suggestion! :-)

This is not easily parsed by machines (or even humans). Some version numbers are on the same line, others are on a separate line.

There's extraneous and unneeded info.

And there's no way to influence the appearance of the output. For example, the ps command as the -w flag to explicitly set wide text output mode.

Another stream, another set of notes. So much "new"!

I try out a new design for Projectors, splitting EventConsumer into two pieces. Test-driving shows how it's about design exploration, not just writing tests.

#Java #EventSourcing #TDD

Notes from my #Java #EventSourcing work, where I looked at event consumers that only get events they're interested in.

Struggled with Java's MethodHandle (docs could be better!), but otherwise works well.

Thoughts about Projector design.

This was all triggered by new functionality that I want to add: the ability to set a date/time when concert tickets go on sale that is separate from when the concert was scheduled (entered into the system).

#EventSourcing #Java

#Oracle zeigt heute mal wieder, was ihnen die #Java Community bedeutet, hm?

Want some Technical Coaching or a #Java Talk (Event-Sourcing, Testing)?

I'm looking to do meetup/user group presentations or technical coaching the week of April 27, and in June so I don't have to fly all the way back home, just to fly back again a soon after.

I love #Java generics (when I get them right, which can take me a while!) and find varargs really useful when refactoring, but they do NOT play well together. Ugh. Guess I'll create an overloaded method to take a List<T> instead.

On my #Java stream last week, I had some frustration with Avro for event payload serialization and decided that JSON was just fine (in terms of performance).

I had thoughts about Projections as Caches and a question around IDs being required in events.

More live coding #Java and #EventSourcing:

I dealt with "external" and "parameter" validation (I didn't implement the third type: "internal" validation) of scheduling conflicts for Concerts.

I also pondered minimal consistency boundaries.

Check out what's new in the #Spring community 👉 https://bit.ly/3NMwcbY

The third milestone releases of: Spring Boot, Spring Security, Spring Integration, Spring AI and Spring AMQP; along with the second milestone releases of Spring Data and Spring for Apache Kafka.

Back to streaming, with notes from yesterday's stream: https://ted.dev/articles/2026/03/23/live-coding-journal-mar-23-2026/

I chatted about consistency boundaries, missing-event heuristics, and encoding (serializing) events.
