Is Elasticsearch 2.x and 5.x officially supported when run on IBM J9 VM (see below).  
The support matrix ([https://www.elastic.co/support/matrix#show\_jvm](https://www.elastic.co/support/matrix#show_jvm)) does not list J9 in any way. So IBM JVM 6 and 7 are excluded explicitly but no hint about IBM J9 VM.

No, it is completely unsupported. In fact, there are known issues. You should use an OpenJDK-based JDK.
