Christopher Schütte commented on PDFBOX-2233:
---------------------------------------------
Tried to upgrade to PDFBox 2.0.3 to get the PreflightParser working without
creating a temp file. PDFBox now has support for parsing without tempfile, but
Preflight is still working the old way. We want to use Preflight in a sandbox
environment where it is unhandy to create files. Can you reopen this issue?
Maybe it was not a good idea to close it that fast.
