Selenium server hangs "unable to create Firefox profile"

I am trying to run a selenium test suite from the terminal using the following command:

java -jar /var/lib/selenium/selenium-server.jar -timeout 60 -htmlSuite "   firefox /usr/lib/firefox/firefox" "http://url " "/test-     case/new/test_suite.html" "/test-case/selenium.html"

      

        
        
        
      

    

executing the above command in terminal outputs as follows ->

After searching online, I found many solutions (up to 2013). The summary of these solutions is the incompatibility between the selenium server and the Firefox version. I tried most of the solutions, but none of them worked.

I am using ubuntu 14.04 (docker-image). Firefox works fine under xvfb..py tests also work fine using selenium python module. The problem only occurs when calling test cases from the terminal.

Selenium server version: 2.45.0 Firefox version: 38.0

A bad solution is required.
