-----------------------------------------
Hi Matt, I've updated to 1602778 and the XML reconfigure cycle works as
expected when invalid XML is encountered. Thanks!

> Key: LOG4J2-619
> URL: https://issues.apache.org/jira/browse/LOG4J2-619
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.0-rc1
> Environment: CentOS 6.5, Oracle Java 7 u55
> Reporter: Sergey Burkov
> Priority: Critical
> Attachments: log4j-r1602630-reconfigure.patch
>
>
> Steps to reproduce:
> 1) auto-reloading of log4j 2.x configuration from XML is enabled
> 2) system is started and producing logs
> 3) change XML configuration, so it's not valid XML any longer
> 4) Wait till it would be picked up -> no more logging info is produced,
> exception can be found from logs (see below).
> 5) Fix XML configuration -> it's not getting reloaded anymore, only java
> restart can fix the problem.
