Thomas Chojecki commented on PDFBOX-1625:
-----------------------------------------
I have some problems with the clone patch :-(
Trying to resolve some OOM and performance issues for PDFBOX-2512 and I'm stuck
with the changes from the clone.patch
The line "return ((RandomAccessBuffer)file).clone();" cause a OOM for documents
with many / large streams. I my case the scratchfile (if I use a
RandomAccessFile) grows to about 140MB. So the only fix for the PDFBOX-2512
issue is to use a RandomAccessFile.
Undoing the clone patch cause four tests to fail.
