Remko Popma updated LOG4J2-716:
-------------------------------
Fix Version/s: (was: 2.1)
2.0.1
> Auto-disable JMX when detecting Android
> ---------------------------------------
>
> Key: LOG4J2-716
> URL: https://issues.apache.org/jira/browse/LOG4J2-716
> Project: Log4j 2
> Issue Type: Improvement
> Components: JMX
> Reporter: Remko Popma
> Assignee: Remko Popma
> Fix For: 2.0.1
>
>
> During the investigation of LOG4J2-703 we discovered that on Android's Dalvik
> VM, Log4J2's JMX components cannot be initialized.
> This can be worked around by setting system property
> {{log4j2.disable.jmx=true}}.
> This ticket is to automatically set that system property when detecting that
> Log4j is running on Android.
> TODO investigate if JMX is not supported at all on that environment or
> whether it can be made to work if invoked correctly. UPDATE:
> {{java.lang.management}} is not supported as of Android API level 20. See
> http://developer.android.com/reference/packages.html
> Stack trace:
> {noformat}
