Subject [jira] Updated: (NET-188) FTPClient#listFiles returns null element when file's timestamp is "02/29"
Date Wed, 12 Mar 2008 20:20:47 GMT

     [ https://issues.apache.org/jira/browse/NET-188?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Sebb updated NET-188:
---------------------

    Attachment: FTPTimestampParserLeap.patch

Patch which appears to solve the Feb 29 problem on Java 1.4.
Can also be applied to NET_2.0 branch if desired.
The patch changes the processing so the short form is always parsed with the current year
appended.
So the short form format string(s) could potentially be changed to include the year.
