Java connection to FileZilla Server

This is the thing, I am trying to connect from java to a FileZilla FTPS Server. I can make the login, but when I try to list the files I get an Exception: 

javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake
    at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:946)
    at sun.security.ssl.SSLSocketImpl.performInitialHandshake(SSLSocketImpl.java:1312)

    at sun.security.ssl.InputRecord.read(InputRecord.java:482)
    at sun.security.ssl.SSLSocketImpl.readRecord(SSLSocketImpl.java:927)

I have tried every possible solution on line, nothing has worked for me, this is the code I´m using (with apache commons-net):

FTPSClient ftps = new FTPSClient();
ftps.setTrustManager(TrustManagerUtils.getAcceptAllTrustManager()); 


ftps.addProtocolCommandListener(new PrintCommandListener(new PrintWriter(System.out)));

int reply;

ftps.connect("xxx.xx.x.xx",8500);
reply = ftps.getReplyCode();

if (!FTPReply.isPositiveCompletion(reply)) {
  ftps.disconnect();
  System.err.println("FTP server refused connection.");
  System.exit(1);
}

if (!ftps.login("user", "*******")) {
  ftps.logout();
}

ftps.setBufferSize(1000);                 
ftps.execPBSZ(0);         
ftps.execPROT("P");
ftps.enterLocalPassiveMode();  
ftps.changeWorkingDirectory("/");
FTPFile[] files = ftps.listFiles();

ftps.logout();

I will really appreciate your help guys. Thanks in advance.

I found the solution. It was something related with the Session reuse, Apache Commons Net has some kind of bug, It does not allow you to reuse the session, I had to implement the cyberduck library cyberduck source code. I hope this helps someone in the future, thanks for your help.
