[jira] Created: (NET-224) NullPointerException if in ftp-directory
are files with creation date Feb 29 current year (Problem of leap year)
NullPointerException if in ftp-directory are files with creation date Feb 29 current year (Problem of leap year)
----------------------------------------------------------------------------------------------------------------
Key: NET-224
URL: https://issues.apache.org/jira/browse/NET-224
Project: Commons Net
Issue Type: Bug
Affects Versions: 1.4
Environment: Java 1.5/1.6
Reporter: Alexander
1) Ant code:
<ftp action="get"
server="${ftp.server}"
userid="${ftp.user}"
password="${ftp.password}"
remotedir="${ftp.dir}"
verbose="yes"
depends="yes">
<fileset dir="${lib}">
<include name="*.jar"/>
</fileset>
</ftp>
NullPointerException if in ${ftp.dir} are files with creation date Feb 29 current year
2) Caused:
Incorrect parse creation date Feb 29 current year
For java 1.5/1.6:
Example 1:
SimpleDateFormat sdf = new SimpleDateFormat("MMM d yy");
sdf.setLenient(false);
System.out.println("date=" + sdf.parse("Feb 29 12:14"));
Result:
date=null;
If doesn't use command sdf.setLenient(false) then result: date = Sun Mar 01 12:14:00 EET 1970
For java 1.4:
Result always "date=Sun Mar 01 12:14:00 EET 1970", because for java 1.4 doesn't throw error NullPointerException
3) Sources:
File: commons-net-1.4.1\src\java\org\apache\commons\net\ftp\parser\FTPTimestampParserImpl.java
Caused in function (line 225: this.recentDateFormat.setLenient(false); ):
public void configure(FTPClientConfig config) {
....
String recentFormatString = config.getRecentDateFormatStr();
if (recentFormatString == null) {
this.recentDateFormat = null;
} else {
this.recentDateFormat = new SimpleDateFormat(recentFormatString, dfs);
this.recentDateFormat.setLenient(false);
}
....
}
