Assertion failure in -[AWTWindow_Panel _validateCollectionBehavior:], /Library/Caches/com.apple.xbs/Sources/AppKit/AppKit-1504.83.101/AppKit.subproj/NSWindow.m:14741
(This message is on 10.12.6, the details are different on 10.13.)
When run under Xcode, there is more information: utility panels cannot be fullscreen primary
My question—does this represent a bug in AppKit that I should report, or is it trying to help me by explaining that my program provided an unsupported set of style bits when creating a window?
