Michael McCandless commented on LUCENE-7779:
--------------------------------------------
Thanks [~jpountz], I agree it's inconsistent now. I'll use the {{boolean\[1]}}
approach ... I wish I could simply return multiple values in Java like I can
from Python.
> OfflineSorter should not call ByteSequencesReader.next again after it returns
> null

> {{OfflineSorter}} uses a simple iterator class, {{ByteSequencesReader}}, to
> step through all {{byte[]}} that need sorting.
> When its {{next}} method returns null the iteration is done.
> But {{OfflineSorter}} then calls next again after that null return ...
