Hi, as virtual threads are being released in a few weeks as part of JDK 21, I was wondering what the status was from this ticket?

+1 for this pinning to be resolved. This is preventing our adoption of virtual threads.

Posted by developer: Added the following to the Connector/J 9.0.0 changelog: "Synchronized blocks in the Connector/J code were replaced with ReentrantLocks. This allows carrier threads to unmount virtual threads when they are waiting on IO operations, making Connector/J virtual-thread friendly. Thanks to Bart De Neuter for contributing to this patch. "
