Tilman Hausherr commented on PDFBOX-2233:
-----------------------------------------
... and that is the problem, sorry. The memory footprint shouldn't increase for
files. The solution should be something that would not use more memory for
files as now, files don't have to be cached in full, but that is what your
patch does.
