That's incredible !I think the the interceptor was used by profile.setRequestInterceptor(WebEngineUrlRequestInterceptor()), so it more or less was referenced by the profile, and it on earth was garbage collected later, that just sounds ridiculous!Please help explain more, thanks !

setRequestInterceptor() doesn't take ownership of the interceptor and you aren't keeping a reference (either implicit or explicit) to it so it gets garbage collected.
