I get an OutOfMemoryException while rendering a file with big patterns at 300

Increasing memory size solves the issue, but 2,7 Gb(!) are needed and that's
not good for our environment.
I have seen a similar issue here:
https://issues.apache.org/jira/browse/PDFBOX-3653
So, I have tried setting maxedge with a smaller value:
java -Dpdfbox.rendering.tilingpaint.maxedge=500 -jar pdfbox-app-2.0.19.jar
PDFToImage -dpi 300 bigpatterns.pdf
That works better: no exception. But the generated image is wrong: a different
tiling is used.
How can I solve the issue?
You can't. Use more space, or a lower dpi.
