Thank you to all. All is working properly.

But may be you have a some idea where can be a problem with that
situation.

Sometimes I am receiving following fatal error:
javax.net.ssl.SSLException: Received fatal alert: unexpected_message
	at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown
Source)
	at com.sun.net.ssl.internal.ssl.Alerts.getSSLException(Unknown
Source)
	at com.sun.net.ssl.internal.ssl.SSLSocketImpl.recvAlert(Unknown
Source)
	at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readRecord(Unknown
Source)
	at com.sun.net.ssl.internal.ssl.SSLSocketImpl.readDataRecord(Unknown
Source)
	at com.sun.net.ssl.internal.ssl.AppInputStream.read(Unknown Source)

First message send to the server is OK and I am receiving proper
answer but afterwards when I am trying to send next message than the
follwoing error occurs.
Server is run in KVM (Kernel-based Virtual Machine).

What type of problem is this?
For the wireshark I saw in Protocol TLSv1:
- ClientHello
- ServerHello, Change Cipher Spec, Finished
- Application Data
- Alert (Level: Fatal, Description: Unexpected Message)

Best regards
