Stackoverflow error when using plantuml gui

Question

I have been using Plantuml gui using the following command.

java -jar plantuml.jar -gui

It worked fine for a while but then suddenly I started getting the following error. Everything has slowed down and diagram images are no longer being generated, the GUI does not list the image files in the folder I have selected. Any help will be much appreciated.

Which versions of plantuml / java are you running (java -Djava.awt.headless=true -jar plantuml.jar). Which OS are you using? Did you recently update the plantuml / the Java version you used? Does it happen with a special diagram or at the beginning? — albert, Feb 18 '19 at 09:27

I have found the problem. The StackOverflowError should have given me an hint, but I missed it. Usually it is related to a recursive loop. I am using the file include feature and had a circular file reference. So plantuml was going (or rather I was sending it) into an infinite loop and therefore it was running out of stack space.
