Subject solr shutdown error
Date Fri, 01 Jul 2016 11:06:13 GMT
hi all,


solr version: 4.9.0


I create and get a HttpSolrServer connection by singleton pattern. I find the method of "shutdown"
in solrj API, so I decided to use "shutdown" to release resources, but I got the error as
below, It is due to singleton pattern?
