>             Project: Solr
>          Issue Type: Bug
>      Security Level: Public(Default Security Level. Issues are Public) 
>    Affects Versions: master (7.0), 6.4.0
>            Reporter: Shawn Heisey

> The new 6.4.0 version includes some significant changes having to do with metrics.  These
changes have broken core swapping.  Will attach some screenshots.
> For the screenshots that I will attach, I started Solr directly from the 6.4.0 download
on Windows 7 (bin\solr start).  Then I created a "foo" core and a "bar" core, each from a
different configset, using the bin\solr command.
>  * Screenshot 1: you can see the two cores in CoreAdmin.
>  * Screenshot 2: Attempting to swap the cores, an error message appears about a metric
already existing for the ping handler.
>  * Screenshot 3: Clicking somewhere else and then back to CoreAdmin shows that both cores
have the same name -- bar.
>  * If Solr is stopped and then started back up, the admin UI looks like screenshot 1
again -- the change that caused two cores with the same name only took place within the running
Solr and did not update files.
