      A DESCRIPTION OF THE PROBLEM :
      Given example doesn't compile. Funnily, all parts of code are essential.

      Minor changes allow it to compile:
      1. Compiles if inner class is removed
      2. Compiles if 'final' is removed from any single field of inner class
      3. Compiles if any single field of inner class is removed
      4. Compiles if any single field of inner class in initialized in field declaration and not in constructor
      5. Compiles if inner class is removed completely
      6. Compiles if "final" is removed from "item" variable

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Compile example code

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      Code compiles
      ACTUAL -
      Code doesn't compile
