AbstractConfiguration should handle UnsupportedOperationExceptions in Iterator.remove() gracefully --------------------------------------------------------------------------------------------------
Key: CONFIGURATION-277 URL: https://issues.apache.org/jira/browse/CONFIGURATION-277 Project: Commons Configuration Issue Type: Bug Affects Versions: 1.4 Reporter: Michael Rudolf Hi, In AbstractConfiguration method clear() on line 533 (see code below) a possible UnsupportedOperationException is not caught resulting in the malfunctioning of the whole method. However, the documentation of the getKeys() method itself warns about relying on the remove() method of interface Iterator. The clear() method should not propagate that exception, it should catch it and try the clearProperty(String) approach if the remove() method is not supported. Iterator it = getKeys(); while (it.hasNext()) { String key = (String) it.next(); it.remove(); <------- EVIL! if (containsKey(key)) { // workaround for Iterators that do not remove the property on calling remove() clearProperty(key); } Best regards, Michael -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
