      The bug

      When specifying a resource pack URL and checksum / hash in the server.properties and the client detects that the checksum does not match for an existing resource pack, it fails deleting it, because the file is already being used by another process.

      Code analysis

      In the method clientPackSource.clearServerPack() only the reference to the UnopenedResourcePack is removed, but the pack is not closed before.
