JEE Town Reading List ::: from JavaSpecialists

Issue 336 - CopyOnWriteArrayList.subList() ConcurrentModificationException

Java's CopyOnWriteArrayList gives us a snapshot iterator for fast reading. However, its subList() is not snapshot, and will break if the list is changed. In this newsletter we look at a way to make a safe subList() copy, using the iterator and an AbstractList.

Issue 335 - ZGC Mysteries

In our previous newsletter we posted a puzzle about ArrayList creation in ZGC. Lots of Java programmers sent in their ideas, and we are still looking for the perfect answer. Here are some more thoughts on the idea, whilst we wait for The Z Garbage Collector Book to arrive.

Issue 334 - ArrayList vs LinkedList Puzzle

Every schoolboy knows that arrays are faster than linked structures, no matter the language. In this newsletter we present a puzzle where we find LinkedList outperforming ArrayList for ZGC. Let's see who comes up with the most thorough explanation why.

Grab Cuts Mechanical Analytics Work From 44% to 30% with AI Agents

Cloudflare Turns CI Pipelines into TypeScript Workflows

Cloudflare has released cloudflare/ci, a CI SDK that defines pipelines in TypeScript on top of Cloudflare Workflows, giving each step durable retries and replay, concurrent steps by default and Sandbox snapshot caching. It targets the Workers runtime and depends on Artifacts, still in private beta, so the transferable lesson is the durable-step model rather than a drop-in CI replacement.
