Date Tue, 13 Dec 2016 17:18:59 GMT

     [ https://issues.apache.org/jira/browse/VFS-625?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Michele Scarpenti updated VFS-625:
----------------------------------
    Description: 
My simple code:
{code:title=SimpleMethod.java|borderStyle=solid}
    private void moveFile(String source, String dest) throws FileSystemException {
        FileObject fileSource = fsManager.resolveFile("ram://virtual/" + source);
        FileObject fileDest = fsManager.resolveFile("ram://virtual/" + dest);
        if (fileSource.canRenameTo(fileDest))
            fileSource.moveTo(fileDest);
    }
{code}

fileSource exist and canRenameTo return true, destination does'nt exist, and parenth folder
doesn't exist too, when i try to "moveTo" it throws NullPointerException:

News:
If I create the dest parent folder, the Exception is not thrown.

  was:
My simple code:
{code:title=SimpleMethod.java|borderStyle=solid}
    private void moveFile(String source, String dest) throws FileSystemException {
        FileObject fileSource = fsManager.resolveFile("ram://virtual/" + source);
        FileObject fileDest = fsManager.resolveFile("ram://virtual/" + dest);
        if (fileSource.canRenameTo(fileDest))
            fileSource.moveTo(fileDest);
    }
{code}

fileSource exist and canRenameTo return true, but when i try to "moveTo" it throws NullPointerException:
