Long lines are corrupted when read by _readNextSlow about java-merge-sort HOT 4 CLOSED

Oh. That's obviously not intentional.
Thank you for reporting this!

I'll be happy to fix that. Do you happen to have a simple reproduction? (I assume you encountered this with some code so in case you have anything that'd help -- I will need a regression test at any rate, to ensure it won't break again).

from java-merge-sort.

Reproduction is very simple, create a file with at least one line of length 40000 (or anything > 2 x 16000).
example.txt

The attaches example file has a single line composed of 16000 '0', 16000 '1' and 15990 '2'.

When you sort this file with TextFileSorter which calls RawTextLineReader (and _readNextSlow), the result is a file with a single line containing only the '0's and '2's, the '1's have been discarded as they occupy the second 16000 block.

How embarrassing. :)

Thank you for reporting the issue; I added a simple test, fixed the issue, and will release 1.0.1 next.
Should be available via Maven Central within couple of hours.

Thanks for the quick fix.
