h2. Steps to reproduce
# Have the following installed:
## FOP 2.9
## Batik 1.17 (which uses/depends on xmlgraphics-commons 2.9)
# Try to process {{<fo:external-graphic
src="file:\\\D:\interlaced_image.png"/>}} (the image has been attached to the
issue)
h2. Expected behavior
A correct PDF is generated
h2. Actual behavior
The above error message is generated
h2. Additional notes
FOP 2.9 with Batik 1.16 works (probably because it uses/depends on
xmlgraphics-commons 2.7), but Batik 1.16 is vulnerable.
