> @shipilev thanks for doing the analysis and reporting the issues. I found 2 leaks. Do you see more that could be related to JDK-8227745 ([40f847e](https://github.com/openjdk/jdk/commit/40f847e2))?

I think those are only two instances. I am only aware of [this one](https://sonarcloud.io/project/issues?fileUuids=AXaE0amt8L9hkQskFrwX&id=jdk&resolved=false&types=BUG). I meant to set up my own some time later.
