Reading List ::: from JavaSpecialists
Issue 328 - Negative size() in LinkedBlockingDeque
The LinkedBlockingDeque has an interesting feature in addAll(), where they first build up the linked nodes and then add them all to the tail. However, a bug allowed us to overflow the size, resulting in a negative count. In this newsletter we look at this bug, and also how it was fixed in Java 26.Issue 327 - ShuffleGatherer
Instead of shuffling our stream at the end in the collect() method, we can also shuffle it in stages using the new stream gatherers. This allows us to shuffle sections at a time and even support infinite streams.Issue 326 - Stream Gathering with a Different Distinct Function
A few years ago, we tried to create a new distinct() function for a Stream. It wasn't pretty. In this newsletter we revisit that adventure using the new Stream Gatherers from Java 24.Issue 325 - Be a Distinguished Java Engineer in the Age of Vibe Coding
We are all amazed how AI can help us in everyday tasks. It can even write Java code. But "Show me the Pull Requests" (Evans) sums it up nicely. We do not (yet) see AI massively improving open source projects.Issue 324 - Sequenced LinkedHashSet
LinkedHashSet implements the SequencedCollection interface, allowing us to addLast(), addFirst() and even reverse the collection. This sometimes causes some surprises.Comment Wall

Hello Juggies!
The time has come for someone else to take the reins with this group. It’s been incredibly rewarding for over 20 years and I thank all of you for your contributions. Hopefully I will see many of you at the next meet up.
Best regards,
Mike
