[jira] Resolved: (CONFIGURATION-403) XMLConfiguration isEmpty has
altered behaviour between 1.4 and 1.6
[ https://issues.apache.org/jira/browse/CONFIGURATION-403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Oliver Heger resolved CONFIGURATION-403.
----------------------------------------
Resolution: Fixed
Fix Version/s: 1.7
Should be fixed in subversion now (revision 902439).
I applied a slightly different solution: IMO the problem was caused by the load() method which used to assign the root node an empty text even if the XML root element had no content. So I added a condition here rather than in the isEmpty() method.
Nevertheless thank you very much for the patch and your analyis.

> Issue Type: Bug
> Affects Versions: 1.6

> Given xml configuration file
> {code:xml}
> <?xml version="1.0" encoding="ISO-8859-1" ?>
> <empty></empty>
> {code}
> {code}
> XMLConfiguration xml = new XMLConfiguration(file);
> assertTrue(xml.isEmpty());
> {code}
> isEmpty() returned true on version 1.4 ?, now it returns false, and the configuration contains a single empty string as key.
> Not sure if this should be considered a bug, but the documnetation reads: Checks if this configuration is empty. Empty means that there are no keys with any values, though there can be some (empty) nodes.
