Sylvain Lebresne updated CASSANDRA-6470:
----------------------------------------
Attachment: 6470.txt
We were not handling empty bounds in DataRange.sliceForKey() (that is indeed
used by paging calls) which was returning an empty slice array (which was
incorrect but hence the error).
Attached simple fix.
