What would be preferable is to have the serviceLoader accept “criteria” (which are callbacks) that can evaluate each of the located services based on any additional properties that are included in the properties file and either eliminate them or return a “ranking".

I understand you may have another use case in mind, but in what concerns jep264's LoggerFinder though - I don't think that would be useful. The JDK can only use one LoggerFinder service implementation, and if more than one is found, it most probably indicates a configuration error - where several implementations have been put by mistake on the classpath. Just taking the first and silently continue could end up in strange misbehavior, where the application's developer would not see the expected debug traces - because she configured one framework but it's the other that happens to be used. I believe it's a better idea to fail fast in this case. best regards, -- daniel
