body: <p>Why an executable jar when run from a command line uses much more RAM - in my case around 7 time more - than the same project run from Eclipse?</p>
  
  <p>While developing the project I run the application from Eclipse (Run->Run) it used around 60mb (I looked at the just created javaw.exe process) of ram, whereas if I create an executable JAR and run it from command line (Windows) the ram usage is about 450mb. Also, the amplitude of ram usage change is more when run from the command line, than from Eclipse's Run->Run.</p>
