------------------------------

>
> Key: JENA-613
> URL: https://issues.apache.org/jira/browse/JENA-613
> Project: Apache Jena
> Issue Type: Question
> Components: ARQ
> Affects Versions: Jena 2.11.0
> Environment: Google App Engine
> Reporter: TipTop Labs
> Assignee: Andy Seaborne
> Priority: Minor
>
> I run into this exception when employing Jena 2.11.0 as part of a Google App
> Engine application.

> 1:10:41,371 WARN [com.hp.hpl.jena.sparql.mgt.ARQMgt] - Failed to initialize
> JMX
> java.lang.NoClassDefFoundError: java.lang.management.ManagementFactory is a
> restricted class. Please see the Google App Engine developer's guide for
> more details.

> 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
> more gracefully e.g. by a Jena/ARQ property setting?
> I noticed in

> is (perhaps) already meant to handle environments where JMX does not exist,
> but apparently this does not cover Google App Engine (where
> {{ManagementFactory}} is not available by
> [design|https://developers.google.com/appengine/docs/java/jrewhitelist]) well.
