To all,
I am contemplating a Java upgrade on some local instances of Zookeeper. I
cannot find any documentation online about the highest compatible version of
Java I can use. The version numbers of both my Solr and Zookeeper instance are
fixed and cannot change.
Solr = 8.1.1
Zookeeper = 3.4.14
Currently, we are using OpenJDK 1.8.202. According to online documentation,
Solr 8.1.1 has been tested through Java 13 (pre-release), which probably means
13 GA will work. Zookeeper just says 1.7+. Does that mean 13 will work with my
version of Zookeeper?
Thanks

For Solr 8, which requires Java 8.x, I would probably go with OpenJDK
11. Java 17 has a bug that Solr 9 can work around, but Solr 8 has no
workaround for it. For Solr 9, I would run OpenJDK 17.
If you are considering upgrading beyond your current release, Solr
8.11.x includes ZK 3.6.2 and Solr 9.3.0 includes ZK 3.9.0 ... which are
going to require a ZK server upgrade.
Thanks,
Shawn
