This is a nasty looking failure ... it tripped on an assert that I
don't think is possible :)

It's this assert:
// We should never see an empty candidate: we iterated over
maxMergeAtOnce
// segments, and already pre-excluded the too-large segments:
assert candidate.size() > 0;
candidate is an ArrayList, and it should always have at least one
element based on the (admittedly rather hairy) logic above ... I
suspect there is an exciting Java 9 hotspot bug here. The failure
doesn't repro on Java 1.8.0_101 nor Java 9-ea+139.
