Tilman Hausherr updated PDFBOX-4219:
------------------------------------
Description:
I get rendering errors and sometimes exceptions in my regression tests. It is
somehow related to several threads initializing standard 14 fonts. It happens
only about every 25 times.
My theory is that one thread accesses the naming table and another accesses the
glyf table. I did try several things in the last months to avoid it, all were
unsuccessful and I lost my notes about it last winter due to a static discharge
on a KINGSTON usb stick.
Here's the output when it doesn't go well:
