Please add - Operating system - How Solr is installed - What your solr.in <http://solr.in/>.sh setup is
I get confused by you using backslash path separator, is this Windows? And it is quite uncommon on use /opt/solr/solr/server/solr as SOLR_HOME in a production install, the default when using the installer is /var/solr/data. I understand you rebooted the machines to downgrade Java - that should not be any problem, though I'd rather upgrade to from 11.0.7 to 11.0.10 than downgrade??
