> The code at CoreContainer.reload(CoreContainer.java:636) correctly throws a Solr Bad Request Exception:

> if (core == null)
> throw new SolrException( SolrException.ErrorCode.BAD_REQUEST, "No such core: " + name );
> {code}
> But then the code at CoreAdminHandler.handleReloadAction(CoreAdminHandler.java:673) catches it and throws the Server Error exception:
> {code}
> try {
> coreContainer.reload(cname);
> } catch (Exception ex) {
> throw new SolrException(SolrException.ErrorCode.SERVER_ERROR, "Error handling 'reload' action", ex);
> }
> {code}
