      Description

      The method "map" in the "SortedTermVectorMapper" class does not check the parameter "term" for the valid values. It throws ClassCastException when called with a invalid string for the parameter "term" (i.e., "var3.map("*", (-1), null, null)"). The exception thrown is due to an explict cast(i.e., casting the return value of termToTVE.get(term) to type "TermVectorEntry").

      Suggested Fixes: Replace the beginning of the method body for the class "SortedTermVectorMapper" by changing it like this:

      public void map(String term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions) {
      if(termToTVE.get(term) instanceof TermVectorEntry)

      { TermVectorEntry entry = (TermVectorEntry) termToTVE.get(term); ... }

      }
