Java 11 Support

[Oren Kleks]

Hi,

We are trying to test Cryostat

1. Does Cryostat support java 11?
2. Is there a special configuration to open RMI ports for JMX? can you supply a sample configuration?

Thanks,

Oren

1. Yes, any JDK version with JFR. For OpenJDK, that means any 11+ as
well as 8u272+.

2. https://github.com/cryostatio/cryostat#monitoring-applications
The bare minimum is to pass '-Dcom.sun.management.jmxremote.port=9091'
in your application's JVM startup flags. This alone should be
sufficient, assuming that your network permits traffic on port 9091,
but we would encourage you to read that section of the linked document
and consider also enabling JMX authentication and SSL if you have not
already done so.

Hope this helps,
