Jaikiran Pai created ZOOKEEPER-3779: ---------------------------------------
Summary: Zookeeper client 3.4.x fails to connect when using Java 14 Key: ZOOKEEPER-3779 URL: https://issues.apache.org/jira/browse/ZOOKEEPER-3779 Project: ZooKeeper Issue Type: Bug Affects Versions: 3.4.14 Environment: Java 14 Reporter: Jaikiran Pai When running on Java 14, the 3.4.x version of `org.apache.zookeeper.Zookeeper` which creates a client to connect to a Zookeeper server, fails to connect against the server. This appears to be due to the use of `InetSocketAddress.toString()` to parse the host name of an unresolved address in StaticHostProvider[1]. The issue doesn't show up in 3.5.x versions of Zookeeper. But given that 3.4.x isn't that old, I thought I'll raise this here and see if it can be fixed and whether a new 3.4.x release is warranted. Furthermore, there was a discussion here[2] which explains the whole details. There's even a discussion in the openjdk net-dev mailing list[3] to see if there are other similar usages in Zookeeper which might be impacted by this change in the JDK 14. I don't have any real experience with this library, so if someone more knowledgable knows whether or not there are other similar usages in this project, please do reply to the net-dev discussion on the openjdk mailing list.
