Michele Scarpenti created VFS-625:
-------------------------------------

             Summary: FileObject method moveTo throws NullPointerException on ram 
                 Key: VFS-625
                 URL: https://issues.apache.org/jira/browse/VFS-625
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.1
         Environment: Windows 10, Intellij IDEA 2016.6.2.5
            Reporter: Michele Scarpenti
            Priority: Blocker


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:
