Andy Seaborne updated JENA-616:
-------------------------------
Description:
In Jena 2.11.0, the equality transform is done before the filter placement.
This order of applying these two optimizations is not optimal if the filter
placement enables the equality transform where it was not going to be applied
before.
JENA-595 pushes filter placement more deeply inside compound patterns so it is
possible that the filter now applies to a smaller pattern where the equality
transform is now valid.
