    Description

      A DESCRIPTION OF THE PROBLEM :
      As recommened by Eclipse IDE Support, I'd like to report my issue to javac team.

      See details, attached source code and analysis already done by Eclipse team here:
      https://bugs.eclipse.org/bugs/show_bug.cgi?id=536978


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile attached java code
      https://bugs.eclipse.org/bugs/attachment.cgi?id=274960

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      javac should generate compilation error the same as Eclipse does:
      >> The return type is incompatible with AbstractDemo<Request,Response>.test(Request)
      ACTUAL -
      javac compiles the code without any errors
