Description

I have created a Solr CoreAdminHandler extension with the goal to swap two cores and remove the old one.

My code looks like this:

SolrCore core = coreContainer.create("newcore", coreProps)
coreContainer.swap("newcore", "livecore")
// the old livecore is now newcore, so unload it and remove all the related dirs
coreContainer.unload("newcore", true, true, true)

After the last statement get executed the Solr log starts printing the following messages forever

61424 INFO (pool-1-thread-1) [ x:newcore] o.a.s.c.SolrCore Core newcore is not yet closed, waiting 100 ms before checking again.

I tried to call the close() method on the SolrCore instance before and after the unload but the result is the same.
