Access Modifiers in XMPPTCPConnection

In the Smack 4.0.x I could change the method proceedTLSReceived and access the method notifyConnectionError in the XMPPTCPConnection class by inheritance.

Now, in the Smack 4.1 it became private and I don't have access to it anymore (unless I change the Smack code).

So I'd like to ask if these things could be protected in the XMPPTCPConnection:

• protected Socket socket;
• protected boolean usingTLS = false;
• protected void proceedTLSReceived() throws ...
• protected synchronized void notifyConnectionError(Exception e)

In this way, the class become more fexible for very specific implementations.
