      I'm not a Java developer but It appears that the code is attempting to get implementors of RemoteAgentFactory. From what I can tell, there are two - MinaRemoteAgentFactory and JNRRemoteAgentFactory. However, it doesn't appear to find either of these two because of the FATAL: Could not find a suitable ssh-agent provider message that it emits. If it did find MinaRemoteAgentFactory, the MinaRemoteAgentFactory.isSupported() function would either return true or log the Could not find Tomcat Native library message.

      I'm not positive that I have the Tomcat native library installed correctly but it appears that it is not even getting to the point where it's checking for the existence of the library. When I installed Tomcat on Windows, I selected the option to include the native library. In the Tomcat logs, it indicates that the native library is being used.
