Known issues using AKKA 2.25.x Fork-Join Dispatcher on JRE 11

Hi guys,

I am considering the risk of running the SUBJ - cannot migrate to 2.26 right now, but need to run on JRE 11 because of the infra upgrade.
Seeing numerous tickets and discussions about the JDK8 ForkJoinPool clone inside AKKA + in some pilot runs it looks like the dispatcher is spending a lot of time in Unsafe.unpark(Thread) compared to when running in JRE8.
Are there any outstanding performance/stability issues around the fork-join dispatcher in 2.25.x not fixed in 2.25.latest?

Thanks!
