Log Search portal not working if only solr needs SSL connection

If Log Search portal uses SSL only for solr (no https protocol is set for the portal, or to communicate with ambari) then it's not working, as nothing enforces the keystore / truststore passwords to load. Loading these passwords should not be enforced only by loading the SSLContext, it should be done if there is a keystrore / truststore location specified - i.e. the portal uses SSL.
