I get the same error with 1.9.0 on MacOS 13.5.2 (M1):

It doesn't seem to affect function though. I click OK and the program seems to work from there.

SOLVED (for me anyway)

I was having the same issue as what people were reporting above. Re-installed everything and same problem.

My solution was to use the Freerouting-1.9.0.jar (instead of the Freerouting shortcut) file to start the program. No Java error was reported, and design rules were now able to be imported from EasyEDA. Don't know how I missed that in the first place.

@Lycosaurus That's a great piece of information, I'll take a look when I get to work on the next release. Thanks!

Also seeing this on V1.9.0 on Linux (since no one else seemed to be running that in the posts I read). Hopefully already fixed for all platforms.
