Tilman Hausherr commented on PDFBOX-3712:
-----------------------------------------
I'm now unable to complete my parallel rendering tests. They don't progress for
a long time but CPU usage is there, so there isn't a deadlock.
I haven't found out much and I might be wrong. I'm also getting OOM exceptions
in files where I didn't get them before

Yes I can reproduce it but you'd need to have the 1000 files and their
renderings.
