We have been using Elasticsearch with AdoptJDK11 + Eclipse OpenJ9 JVM and it has worked well for the most part. We have lately been seeing some weird issues related to Garbage Collection and so were wondering why Elasticsearch does not support IBM J9 or OpenJ9.
Our Elasticsearch version is 6.8.3. Is there a specific reason why OpenJ9/IBM J9 are not supported?
Usually we don't support a JVM/OS/etc due to a lack of broader use, so the effort involved in testing and fixing issues isn't worth the amount of use we see from it.
