[jira] Commented: (CONFIGURATION-439) Should be possible to disable default error log listener

["Oliver Heger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CONFIGURATION-439?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13002993#comment-13002993 ] 

Oliver Heger commented on CONFIGURATION-439:
--------------------------------------------

Would it make sense to add an option to the _header_ section of the configuration definition file read by {{DefaultConfigurationBuilder}} which controls whether an error listener is added or not? Or how would you like this option to be enabled or disabled?

> The current version of Commons Configuration always adds a default error listener that logs internal errors. This causes an exception to be logged when, for instance, an optional include from a DefaultConfigurationBuilder is not found. The default error listener can be removed with clearErrorListeners(), but this is not easily possible when recursively including a DefaultConfigurationBuilder config in a DefaultConfigurationBuilder config.
> It should be possible to disable the default logging of internal errors, or at least disable the default logging of non-existent optional configuration files.
