I am trying to read a file from a samba share. For this I want to use the jcifs-ng lib. Threfore I got the jcifs-ng jar (version 2.1.10) and added it to my build path and wrote the following code:

SmbFile folder = SMBFileFactory.produceFileWithGuestCredentials(Constants.SMB_PATH_IMPORT_DIRECTORY);
    if(folder == null)
        return null;
    try {
        return folder.listFiles(new SmbFilenameFilter() {

whereas

public static SmbFile produceFileWithGuestCredentials(String path) {
        try {
            BaseContext bc = null;
            Properties p = new Properties();
            bc = new BaseContext(new PropertyConfiguration(p));
            CIFSContext cc = bc.withGuestCrendentials();
            SmbFile file = new SmbFile(path, cc);
            return file;
        }catch(MalformedURLException | CIFSException e) {
            Logger.logExceptionSysOutEncapsulated(e, SMBFileFactory.class);
            return null;
        }
    }

After testing, I recognized, that a bouncy castle lib is needed to get jcifs-ng running. So I got the bcprov jar (version 1.78.1) and added it as well to my build path. Another test now runs into the following error at the folder.listFiles call:

Exception in thread "main" java.lang.ClassCastException: class org.bouncycastle.asn1.DLApplicationSpecific cannot be cast to class org.bouncycastle.asn1.ASN1TaggedObject (org.bouncycastle.asn1.DLApplicationSpecific and org.bouncycastle.asn1.ASN1TaggedObject are in unnamed module of loader 'app')

After a little googling, I just found out, that I should use the “right” version of bprov… But what is the right version, if not the latest(1.78.1)?
Anyone know what my issue is?
