Description

Cassandra does not currently support the new JVM, Eclipse Openj9. In internal testing, Openj9 outperforms Hotspot. I have deployed a modified jamm library that has a problem with the current startup, but when I started Cassandra, I got a log message saying "Non-Oracle JVM detected." Some features, such as unimported compact SSTables, may not work as intended "If there is no problem, I would also like to delete the above message.
