Andy Seaborne commented on JENA-613:
------------------------------------
Only JMX is disabled.
This has been changed slightly in 2.11.1 (development). The logging is at
level "debug" and the full stacktrace is not printed.
(What is not clear is how monitoring of an application is supposed to happen
unless it's by google-only APIs and tools.)

> Is it safe to assume that this will only disable ARQ’s JMX agent and not
> otherwise impact Jena and the application? And is it possibly to disable JMX
