We are currently working on a new logging framework. That work is being 
tracked in this JEP:

JEP 158: Unified JVM Logging
http://openjdk.java.net/jeps/158

As part of that work it will be possible to configure the logging during 
runtime, as stated by this bullet:

"Logging can be configured dynamically at runtime via jcmd or MBeans"

Thanks,
Bengt
