Tilman Hausherr commented on PDFBOX-5876:
-----------------------------------------
The JPX image in that file is 7020 x 4964, which is quite big, and -Xmx600m is
quite low. But I noticed that the subsampling parameter wasn't used when
reading the JPX image the second time, which was the cause for the OOM. (JPX
images have to be read twice because of some weirdness in the specification) It
should work now, I tried it with PDFDebugger, which doesn't allow to set a temp
cache.
> This jpeg2000 takes up a lot of memory, causing overflow.
