Manuel Aristaran commented on PDFBOX-2996:
------------------------------------------
Hi [~lehmi], sorry for the delay.
I'm attaching a patch that brings the iterative Quicksort implementation that
we use in Tabula
(https://github.com/tabulapdf/tabula-java/blob/cbde485b40ad3b65b1cfc878bd7e085a23c34d37/src/main/java/technology/tabula/QuickSort.java)
The current test suite passes, but I haven't included any new tests.
Regarding licensing: you can assume that I'm relicensing that code PDFBox as
Apache 2.0. Let me know if there's anything else we should do.
Hope it helps!
