Hi, I am glad to share with you that we are now part of the OpenJDK Quality Outreach Program.
https://wiki.openjdk.java.net/display/quality/Quality+Outreach This means that we will be actively reporting any issue found by ZooKeeper project to the OpenJDK team. We are currently testing ZooKeeper against a matrix of versions of the JDK and current master is running very well on JDK8,11,12,13,14 and 15-EA. You will see on this list periodically an email from the OpenJDK team. I will take care of responding to these emails. I am happy that we can contribute back to the OpenJDK project. This activity will also help us in keeping ZooKeeper in perfect shape on every OpenJDK version. Best regards Enrico Olivelli
