Description
For full support of Virtual Threads, several sub-tasks need to be done:
- Avoid Lengthy and Frequent Pinning by replacing synchronized blocks with ReentrantLocks (use the option -Djdk.tracePinnedThreads=full to print stack traces when a thread blocks while pinned)
- Don't Cache Expensive Reusable Objects in Thread-Local Variables by avoiding thread locals when possible since when using Virtual Threads, the objects will never be reused so if the thread-local variables are never reset, it will end up with an OOME.
- Use Semaphores to Limit Concurrency instead of relying on the size of the thread pool when applicable
- Allow to expose ThreadPerTaskExecutor through JMX indeed so far it is limited to ThreadPoolExecutor
