Use ReentrantLock instead of synchronized to avoid deadlock on pinning

Open oddbjornkvalsund opened this issue 3 months ago • 0 comments

DeserializerCache uses synchronized to protect the _incompleteDeserializers map from concurrent modification. This deadlocks when using virtual threads + IO within the synchronized block and you end up with a non-responsive VM and stacktraces looking like the one below. Note in particular the threads that have - waiting to lock <0x00000006104ab5e8> (a java.util.HashMap).

Replacing the synchronized keyword with a ReentrantLock fixes the problem. See relevant info here: https://www.infoworld.com/article/3713220/java-virtual-threads-hit-with-pinning-issue.html and here: https://inside.java/2024/02/21/quality-heads-up/.
