I18NBean getText method spamming EAC logs

The new biggest source of log errors as at 28/05/09 is com.atlassian.confluence.util.i18n.DefaultI18NBean's getText(String key, Object[] args) method:

230 ERROR [confluence.util.i18n.I18NBean.getText] Error formatting internationalized string with key: 
    This is the {gliffy} macro which converts Gliffy Attachments to images you can see on a page
230 ERROR [confluence.util.i18n.I18NBean.getText] Error formatting internationalized string with key: 
    Required. The {mockup} macro displays the ui mockup in the page.

The URL for these errors is /plugins/macrobrowser/browse-macros.action so it looks like a problem with the Jsonation of the macro's description Message object. Namely, that getText(Message message) in DefaultI18NBean delegates to getText(String key, Object[] args) with the message arguments which calls java.text.MessageFormat.format(result, args) even if the args == null. As the message text contains a placeholder

or

an IllegalArgumentException is thrown.

Couldn't the MessageFormat.format call be skipped if the Message args are null or an empty array? Even if the message text could be parsed by MessageFormat the placeholder substitutions wouldn't do anything.
