Whenever I try to use a custom resource pack for a server I crash.

What I expected to happen was that I would easily get the resource pack to play this minigame.

What actually happened was that the computer crashed and the summary was:
java.lang.IllegalArgumentException: Parameter 'directory' is not a directory

Steps to Reproduce:
1. Say yes to downloading the custom
resource pack.
2. Just wait for the crash to roll in.

P.S. I did try by entering "enabled" for resource packs. It still crashed my game.
