OrlandoJUG Reading List ::: from JavaSpecialists
Issue 283 - Four Billion Changes
A nice puzzle to brighten your day - how can we make the Iterator think that the List has not been changed?Issue 282 - Biased locking a goner, but better things Loom ahead
Biased locking has made unnecessary mutexes cheap for over a decade. However, it is disabled by default in Java 15, slated for removal. From Java 15 onwards we should be more diligent to avoid synchronized in places where we do not need it.Issue 281 - Puzzle 2: Is it garbage?
In our next puzzle, we up the ante a bit. We prevent GC during the test() method by storing a strong reference to all our Vectors. Cock and bull story, or are we struggling to identity our biases?Issue 280 - Puzzle: What's up with Vector?
For today's puzzle, we are getting elements from Vector, sequentially and in parallel. But why is the performance so much worse in Java 15-ea+28?Issue 279 - Upgrading ReadWriteLock
The Java ReentrantReadWriteLock can never ever upgrade a read lock to a write lock. Kotlin's extension function ReentrantReadWriteLock.write() cheats a bit by letting go of the read lock before upgrading, thus opening the door for race conditions. A better solution is StampedLock, which has a method to try to convert the lock to a write lock.Comment Wall
