Reading List ::: from JavaSpecialists
Issue 320 - Please Don't Yield A Lot
Java's Thread.yield() traditionally would cause a voluntary context switch. However, with virtual threads, it causes the thread to be unmounted from its carrier thread. This can greatly increase the user and system time for ALL the carrier threads. And there is no way to turn it off. Keep an eye out for yield in your thread dumps.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.Comment Wall
