Tilman Hausherr commented on PDFBOX-4525:
-----------------------------------------
It is not a good idea to work with old versions… the best would be to find out
when the memory problem started, by checking out different revisions to find
out which one is the culprit. Something similar to "git bisect" but with svn.
(But there is a git mirror on github). It takes several hours but can be done
in parallel to other tasks but you need patience and a good test tool.
