How do I generate a name from that folder and compare it with already registered JDKs, without registering it first ;) Thats why it uses display name right now. It knows how to build that name if it registers JDKs, so it can check for JDKs which are already registered and skip the step if they are. Having access to the path of registered JDKs would allow this too, but honestly I would probably also check the display names too since we don't want to register JDKs with the same name in the list in case of name clashes. -- This is an automated message from the Apache Git Service.
