Components: ARQ
Affects Versions: Jena 2.11.2
Environment: java 8
Reporter: Andy Seaborne
Assignee: Andy Seaborne
Behaviour has changed; testing/ARQ/Optimization/opt-top-10 illustrates this.
TopN was buggy but happened to work with Java7 and before. Something in Java8
behaves differently (PriorityQuery? some sort of hash orderingso data is
presented differently?)
