[jcifs] NullPointerException when doing SmbFile.listFiles()

[Arjan van der Veen]

Hi,
I get a NullPointerException that I can't explain. I try to connect to an
Apple TimeCapsule with Windows file sharing enabled with the following unit
test:

        jcifs.Config.registerSmbURLHandler();
        NtlmPasswordAuthentication auth = new
NtlmPasswordAuthentication("PALANTHIR", "arjan", "*********");
        SmbFile smbFile = new SmbFile("smb://192.168.129.21/arjan/pw.txt",
auth);
        System.out.println("isdir: " + smbFile.isDirectory() + " exists: " +
smbFile.exists());
        SmbFileInputStream sfis = new SmbFileInputStream(smbFile);
        byte[] b = new byte[8192];
        int n;
        while ((n = sfis.read(b)) > 0) {
            System.out.write(b, 0, n);
        }
        smbFile = new SmbFile(smbFile.getParent(), auth);
        smbFile.list();

The reading of the file works perfect, the listing of the subfile of a
directory results in the following stacktrace:

Anyone an idea? I use jcifs-1.3.3.

Thanks in advance.

Arjan
