FTP throw NullPointerException when enountering 02-29-2008 (leap year bug)
--------------------------------------------------------------------------
Key: NET-193
URL: https://issues.apache.org/jira/browse/NET-193
Project: Commons Net
Issue Type: Bug
Affects Versions: 1.4
Environment: Ant 1.7
commons-net-1.4.1
java 1.6.0_01
Windows 2003 (build machine)
Windows 2003 FTP server
Reporter: j burtram
ant FTP task blowing up when parsing directories containing ANY items dated
(created/modified) February 29 2008.
There may be a workaround using defaultDateFormatConfig or
recentDateFormatConfig - but I didn't find it (actually by messing with some of
the ftp attributes my build finally stopped throwing NullPointerExceptions, but
refused to list or get any files!! Always came back with 0 files found)
Not sure the date format used by Windows FTP server - One thing I am sure of:
tasks that once worked stopped working on Friday - it took all weekend and most
of today to figure it out. By updating files and folders, magically ftp task
begins working agains and I slowly begin regain my sanity
Here's the exception:
