#### OpenJ9
The [OpenJ9](https://eclipse.dev/openj9/) JVM is a more memory-efficient alternative to the HotSpot JVM, at the cost of
slightly slower throughput.
IBM provides precompiled binaries for OpenJ9
named [Semeru](https://developer.ibm.com/languages/java/semeru-runtimes/downloads/).
This is the JVM used in the [Docker image](https://github.com/Athou/commafeed/blob/master/Dockerfile).
