Reading List ::: from JavaSpecialists
Issue 324 - Sequenced LinkedHashSet
LinkedHashSet implements the SequencedCollection interface, allowing us to addLast(), addFirst() and even reverse the collection. This sometimes causes some surprises.Issue 323 - Visiting All Threads (Including Virtual)
In this newsletter, we explore how we can visit the entire hierarchy of threads in our virtual machine, including virtual threads. We do this using the composite, visitor and facade design patterns.Issue 322 - Throwing InterruptedException Early
The LinkedBlockingQueue and LinkedBlockingDeque behave slightly differently when methods put() and take() are called by a thread that happens to be in the "interrupted" state. The LBQ throws an InterruptedException immediately when we call take(), even if the queue contains elements. The LBD, however, only throws InterruptedException if the deque is empty and the thread would enter the WAITING state. In this newsletter we show how a dynamic proxy can make the behaviour consistent.Issue 321 - StampedLock ReadWriteLock Dangers
ReentrantReadWriteLock has a limit of 65536 concurrent read locks. That is an unattainable number with platform threads, but definitely achievable with virtual threads. In this newsletter we explore some of the issues if we want to switch to the StampedLock.asReadWriteLock() instead.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.Comment Wall
