Are the IntelliJ instructions missing -Dairsonic.development=true?

[simojenki]

I followed the instructions found here -> https://airsonic.github.io/docs/developer/intellij/, however the application would not start. Instead I got the following exception;

I was able to move past this error by setting the following system property;

-Dairsonic.development=true

[muff1nman]

Nope, it works fine without that property. I'd go back and check the instructions.

Works fine for me too without that instruction I guess? If you do find what was wrong without it let us know!
