HTTP request logging

[Pekka Enberg]

As I am debugging a JMX startup hang (#100), I need more visibility into what the JMX proxy is doing internally.

I wanted to trace HTTP requests, but I am unable to get anything out of Jersey, even with the LoggingFeature capability in Jersey 2.30.1:

@tarzanek, @amnonh, any ideas how to get this working?

adding sample from Amnon:
"
Example a log.properties file I used myself as an example
you should add to the java command line
-Djava.util.logging.config.file=log.properties

I believe the scylla-jmx passes all -D command line variables to the internal java, so it should work (I've edited the scylla-jmx locally and added it to the java call part so I will not need to remember how to do it).

so it should work by calling:
scylla-jmx -Djava.util.logging.config.file=log.properties
"
log.properties.txt
