SVG image raises java.lang.UnsupportedOperationException for output type EPS

Question

I have been using PlantUML in conjunction with Sphinx for quite a while now, which worked great thus far. Thanks a lot for this awesome tool!

Unfortunately I am having trouble with the PDF generation, though. The trigger seems to be referenced SVG images. I narrowed it down to the EPS output format being the culprit here. When generating via:

java -Djava.awt.headless=true -jar plantuml.jar -teps issue.puml

I get this exception:

java.lang.UnsupportedOperationException: class net.sourceforge.plantuml.ugraphic.UImageSvg class net.sourceforge.plantuml.ugraphic.eps.UGraphicEps at net.sourceforge.plantuml.ugraphic.AbstractUGraphic.draw(AbstractUGraphic.java:87) at ...

Switching to output format SVG via:

java -Djava.awt.headless=true -jar plantuml.jar -tsvg issue.puml

works fine though!

The diagram used to trigger this exception looks like this:

@startuml

svg : <img:drawing.svg>
png : <img:drawing.png>

png -up-|> svg: SVG <img:drawing.svg> expected
png <|-up-- svg: PNG <img:drawing.png> expected

@enduml

Any ideas how to solve the issue?

Cheers,

P.S.: the test images (PNG and SVG) are these:

I retried with PlantUML 1.2020.12 but unfortunately still to no avail.

Any hint really appreciated!
