Hi Grant,
You can see the relevant junit output below. It looks like the
SparseMatrix/SparseVector failures are caused by
SparseVector.asFormatString() serializing the key/value pairs in
arbitrary order.
I've attached a patch against revision 670280 that causes ordering by
keys (i.e. ascending vector index). Please let me know if I've
misunderstood asFormatString(), or if there is a better way to submit
a patch.
I'm looking into the CanopyCreation failure now...
