I found that it happens because a bug in the following infinite 
loop in the NutchAnalysis class. 

label_4:
      while (true) {
        switch ((jj_ntk==-1)?jj_ntk():jj_ntk) {
        case 0:
        case PLUS:
        case MINUS:
        case COLON:
        case SLASH:
        case DOT:
        case ATSIGN:
        case APOSTROPHE:
        case WHITE:
          ;
          break;
        default:
          jj_la1[6] = jj_gen;
          break label_4;
        }
        nonTerm();
      }

It seems that this class was generated using JavaCC. Could 
anybody who knows how to use this tool fix the problem?
