When I tried starting headless BehaviorSpace for the 7.1 preview version, I tried using the batch file (working on Windows).
The following error message was the result:
Error: Could not find or load main class Files\NetLogo
Caused by: java.lang.ClassNotFoundException: Files\NetLogo
This must be an error in the batch script. It still works in NetLogo 7.0.3, but not in 7.0.4 anymore.
After this test, I realized I should have used NetLogo_Console.exe.
So, I consider this a minor issue.
