[jira] Commented: (JCR-1285) ObjectContentManagerImpl.getObject(Query) throws NoSuchElementException when query does not match an object

Felix Meschberger commented on JCR-1285:
----------------------------------------

Thanks for reporting and the patch. In fact the method is defined to return null if no object matches the query. Therefore I fix the issue as follows:

            return result.isEmpty() ? null : result.iterator().next();
