[Bigdata-developers] minor bug in ASTDistinctTermScanOptimizer.java

[Jeremy J C. <jj...@sy...>]

bigdata-rdf/src/java/com/bigdata/rdf/sparql/ast/optimizers/ASTDistinctTermScanOptimizer.java

line 381 (in master) reads:
   final long newCard = (long) (1.0 / arity);

the comment above says:

   newCard = oldCard * 1.0 / arity(context, sp)

I suspect the comment is correct and the code is wrong.

(I have no idea what code this is: I had a case of an obviously incorrect estimate cardinality and was looking for an int/long bug, and found this instead)
