Issue 319 - ArrayBlockingQueue: Weakly Consistent Iteration Powered by Weak References

Like many other concurrent collections, the ArrayBlockingQueue sports a weakly-consistent iterator. However, the ArrayBlockingQueue always has a maximum capacity, the length of the underlying array. In this newsletter we explore what happens to pending iterators when we wrap around the circular array.

Issue 318 - Getting Rid of Unused Warnings with _

We sometimes are forced by the Java language to declare variables that we never use, attracting the ire of the javac compiler. Since Java 22 we have a way to declare these as "unnamed" by using an underscore.

Issue 317 - Explicit vs Diagnostic GC

How many times have we seen programmers call System.gc() to "help the garbage collector"? Unfortunately far too often, with potentially terrible performance implications. In this newsletter we explore the explicit and the diagnostic GC and how we can force a GC, even if explicit GCs are disabled.

Issue 316 - Code Before super() - JEP 447

Java 22 preview allows us to write code before the call to super(). There are restrictions. We are not allowed to refer to "this" in any way. We thus cannot set fields before calling the superclass constructor. But what if the superclass constructor calls our methods? In this newsletter we explore a workaround using ThreadLocals.

Issue 315 - Random Newsletter

Classes java.util.Random and java.util.SplittableRandom didn't used to have a common ancestor, making it difficult to write methods that take either. This was finally fixed in Java 17. Let's have a look at some random Java topics together.
