Adriano Machado updated CAMEL-20199:
------------------------------------
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}}
