Yes, that was a bug, and it did skew the results in a way that erroneously
favored both supporting SAM classes and nonlexical "this".  The corrected
stats for openjdk6 are below.  The corrected code can be downloaded from

Total anonymous classes: 1177
But with no constructor args: 1089
And defining only one method: 900
And where the type is a SAM type: 828
  Those that are recursive: 0
  Those that reference 'this': 2
  Those that reference an enclosing 'this': 49
  Those that are interfaces: 771
  Those that are classes: 57
Total distinct interfaces: 48
Total distinct classes: 11
