                .addPermissionOverride(guild.getPublicRole(), null, EnumSet.of(Permission.MESSAGE_READ))
                .addPermissionOverride(getAdminRole(), EnumSet.of(Permission.MESSAGE_READ), null)
                .addPermissionOverride(guild.getMemberById(User.getId()), EnumSet.of(Permission.MESSAGE_READ), null)
                .complete();

This seems to be a bug in versions older than 4.2.0_174 . I recommend you update to fix this issue.

Why does this happen?

When you create a channel in a category using Category#createTextChannel it will first apply all the permission overrides from that category. After this, you apply your manual overrides which might collide with the existing overrides from the category. Due to a bug this would end up with 2 overrides in the request. This causes inconsistent output that can cause strange results.
