Subject [jira] [Updated] (IO-547) Nullpointer Exception in FileSystemUtils.freeSpaceWindows
Date Sun, 13 Aug 2017 15:20:00 GMT

     [ https://issues.apache.org/jira/browse/IO-547?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Nikhil Shinde updated IO-547:
-----------------------------
    Description: 
In FileSystemutils.freeSpaceWindows(String path,long timeout) , path cannot be null. In this
function for following assignment
          path = FilenameUtils.normalize(path,bool), path is assigned null value when 
          (1) path argument is null.
          (2) path argument is illegal/invalid path as per windows system.

{code:java}
public class FileSystemutilTest {
	public static void main(String args[]){
		FileSystemUtils fsuobj = new FileSystemUtils();
                String path = ":\\Users\\nikhil\\Desktop\\tests";  \* Invalid path, causes
Nullpointer Exception*\
		try {
			long space = fsuobj.freeSpace(path);
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
{code}

For above test case, as path is illegal for windows system, Nullpointer exception occurs.
A check for validity of path as per windows file system, will resolve this bug.
