Frank, Thanks for reporting, there may be several users hitting this common issue without even being aware of it
My guess is that the bug you're facing is related to https://bugs.openjdk.org/browse/JDK-8274349 and it has been fixed in openjdk 11.0.17. Pulsar 2.10.2 should be compatible with JDK 17 at runtime even though there are no tests and it's recommended to test it in your dev environment. Pulsar 2.11.0 and onwards will REQUIRE jdk 17 on the server side. Pulsar 2.11.0 rc2 includes openjdk 17.0.5 that contains the above fix.
