When I try to play minecraft on a server that has a custom resource pack, I get this message when it tries to download it: Simply updated a local server I created yesterday on 1.8.6 to 1.8.7. Flat world. Attempting to join succeeds then dc's with the error "Internal Exception: java.lang.IllegalArgumentException: Parameter 'directory' is not a directory". I have tried creating a new folder in my .minecraft directory called 'server-resource-packs', but this doesn't help.
This bug seems to already have been reported here: MC-81019. It was marked as resolved, but this bug definitely is not resolved.
Thank you for your time!
MC-81019 was resolved as a dupe of MC-81082.
This ticket is also a dupe of the latter.
