Joern Kottmann commented on OPENNLP-722:
----------------------------------------
When you ensure the feature ids are assigned identical while running on Java 7
and Java 8 the outcome is identical too. I believe there is some code which
depends on the ordering of the features ids in the context. Maybe not all
computations done in the code are independent of the ordering.
Anyway, I spent quite some time to find these two places mentioned above, and
stopped at that point.
>Looks like this issue comes from changes in Java 8's floating point arithmetic.
Was there a change? I googled that and coundn't find a reference.
> PerceptronPrepAttachTest fails only on Java 8
