This is my fault - I discovered this myself a few days ago. I've been meaning
to file a jira ticket and have not gotten around to it yet.
You can also work around it like this:
CoreContainer container = new CoreContainer(loader) {
// workaround since we don't call container#load
{initShardHandler(null);}
};
