Hi, I've found an issue in displaying of Swap Space at Solr Admin page. When swap page is not used, the admin page shows a NaN percent of usage. Since used and total space are stored in double variables, the result of division of the used space (0.0Mb) by the total space (0.0Mb) is NaN. Maybe it's better to filter this case and put here something like "not used" instead of "NaN"?
