Ok gotcha, archlinux-java get showed a setting of java-8-openjdk/jre. Switching temporarily to java-11-openjdk allowed me to build successfully. Thanks for the help!

@alhirzel: It's a known bug in community/java-xmlgraphics-common package. Should be fixed in java-xmlgraphics-common:2.4-2 If problem persists you can switch your default java runtime

I think this is broken, I get errors early in the compilation process regarding the documentation:

Not stupid at all. Besides, without your initial patch in the first place, I'd have had no clue where to begin looking. Thanks for the fix!

@frankspace: Thanks for the help, it's now working back again.

I've just realized, it was in my original python3.5.patch three years back me so stupid ;)

I solved it! There's a second place where the python version needs to be detected. Here's my updated patch that allows compilaton to succeed:

I hope that helps! Thank you!
