[xwiki-users] problem after update to 7.1.1

Hi, I have update the XWiki 6.2.2 to 7.1.1 with using "apt-get upgrade xwiki-enterprise-tomcat7-mysql" on Ubuntu server with success. But when I restart the Xwiki, they are the following message in the catalina.out file: 2015-07-30 15:31:10,713 [localhost-startStop-1] INFO o.x.s.s.i.EmbeddedSolrInstance - Started embedded Solr server.
