FileAclStore / FileMethodStore Problem by load from File (ResourceAsStream)

I can not load File with AclStore and MethodStore.
In row 48 in FileAclStore:
input = new InputStreamReader(FileAclStore.class.getResourceAsStream("/" + name + ".acl"));
In row 48 in FileMethodStore:
Reader reader = new InputStreamReader(FileMethodStore.class.getResourceAsStream("/methods.acl"));

(Solution -> without slash?)

FileAclStore:
input = new InputStreamReader(FileAclStore.class.getResourceAsStream(name + ".acl"));
FileMethodStore:
Reader reader = new InputStreamReader(FileMethodStore.class.getResourceAsStream("methods.acl"));
