Subject solr shutdown error
Date Sat, 02 Jul 2016 04:59:18 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?
