YADE client connection hangs for FTPS protocol

Current Situation

• YADE is intended to support FTPS as a source and a target for file transfer.
• For the YADE release 1.8.2 file transfer from localhost source to a target over FTPS protocol hangs.
• The error message received by the YADE Client:

  main ERROR 14:12:35,279   (SOSVfsFtpS.java:92) ::connect (@mp.sos:990) connect returns an exception
  com.sos.JSHelper.Exceptions.JobSchedulerException: (@mp.sos:990) org.apache.commons.net.ftp.FTPConnectionClosedException - Connection closed without indication.

Desired Behavior

• YADE should support both Explicit Client Security and Implicit Client Security, see Wikipedia.
• An additional parameter is required that allows to switch between Explicit and Implicit Client Security.
• The use of server side public keys is supported, i.e. the YADE Client can make use of locally available public keys.
• Currently YADE implements Excplicit Client Security, however, this feature is broken and FTPS support should be restored.

Implemented Behavior

• Version 1.8.*
  • FTPS support is restored
    • only Excplicit Client Security
• Version 1.9.*, 1.10
  • FTPS support is restored
  • New features
    • Excplicit/Implicit Client Security
      • Parameter (source_| target_)
        • ftps_client_security = explicit (default) | implicit
          • typo error in release 1.9 (ftps_client_secutity), fixed for release 1.9.1, 1.10, see JADE-296
    • Proxy via SOCKS
    • Trust Manager
      • Parameter (source_ | target_)
        • keystore_type = JKS(default) | JCEKS | PKCS12 | PKCS11 | DKS
        • keystore_file = <path to the keystore file>
        • keystore_password = <keystore password>
      • Samples keystore
        • Generate a Java keystore and key pair

          C:\Temp>keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -keysize 2048
          

        • Import the file, contains the public key certificate

          C:\Temp>keytool -import -keystore keystore.jks -storepass password -file proftpd.cert.pem
          

        • Jade configuration

          target_keystore_type = JKS
          target_keystore_file = C:\Temp\keystore.jks
          target_keystore_password = password
