> This happens due to the following lines in

> {noformat}
> int lowerWindowIndex = Collections.binarySearch(boundaries,
> minTimestamp == null ? Long.MAX_VALUE : file.getMinimumTimestamp());
> int upperWindowIndex = Collections.binarySearch(boundaries,
> file.getMaximumTimestamp() == null ? Long.MAX_VALUE :
> file.getMaximumTimestamp());
> {noformat}
> These return negative values if the element is not found and in the case the
> values are equal we get the exception.
