After many trials and failures the only method that worked for me reliably was to go old school and use FileInputStream and FileOutputStream like so:

   `SmbFile[] files = getSMBListOfFiles(sb, logger, domain, userName, password, sourcePath, sourcePattern);

    if (files == null)
        return false;
    output(sb, logger, "      Source file count: " + files.length);
    String destFilename;
    FileOutputStream fileOutputStream;
    InputStream fileInputStream;
    byte[] buf;
    int len;
    for (SmbFile smbFile: files) {
        destFilename = destinationPath + smbFile.getName();
        output(sb, logger, "         copying " + smbFile.getName());
        try {
            fileOutputStream = new FileOutputStream(destFilename);
            fileInputStream = smbFile.getInputStream();
            buf = new byte[16 * 1024 * 1024];
            while ((len = fileInputStream.read(buf)) > 0) {
                fileOutputStream.write(buf, 0, len);
            }
            fileInputStream.close();
            fileOutputStream.close();
        } catch (SmbException e) {
            OutputHandler.output(sb, logger, "Exception during copyNetworkFilesToLocal stream to output, SMP issue: " + e.getMessage(), e);
            e.printStackTrace();
            return false;
        } catch (FileNotFoundException e) {
            OutputHandler.output(sb, logger, "Exception during copyNetworkFilesToLocal stream to output, file not found: " + e.getMessage(), e);
            e.printStackTrace();
            return false;
        } catch (IOException e) {
            OutputHandler.output(sb, logger, "Exception during copyNetworkFilesToLocal stream to output, IO problem: " + e.getMessage(), e);
            e.printStackTrace();
            return false;
        }
    }`
