> Using monitorInterval with YAML config file format causes JSONParseException
> ----------------------------------------------------------------------------
>
> Key: LOG4J2-976
> URL: https://issues.apache.org/jira/browse/LOG4J2-976
> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators, Core
> Affects Versions: 2.0.2, 2.1, 2.2
> Reporter: Matt Quinn
> Priority: Minor
>
> If, when using the YAML configuration file format, the monitorInterval config
> attribute is configured in order to automatically reconfigure logging, a
> JSONParseException is thrown when the configuration file is reloaded after
> the file changes.
> This appears to be because the YamlConfiguration class does not override the
> reconfigure() method from the Reconfigurable interface. The base class
> implementation is called, which assumes a JSON-style grammar instead of YAML.
