title: swt browser No more handles Error
body: <p>I wrote a simple program. just a CTabFolder and a WelcomTab inherent from CTabItem. I want to fill my WelcomeTab by a browser which render my htmls. at the init() method of WelcomeTab I Create a Browser but when program want to construct it I get this Error</p>
  
  <pre><code>Exception in thread "main" org.eclipse.swt.SWTError: No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

  <p>...</p>
  
  <p>in addition I Use Eclipse 3.7 on KDE based on Arch-Linux
  as I searched for this Error everywhere tells about handle limited on threads, but this is simple program with no Font or Image ... to dispose. I think it should be a problem about gain handle from Operation System</p>
