Solr includes it's own copy of Spring which causes class loading issue. To address this issue, Solr is now configured to use the portal class loader instead of spring's class loader.

To manually fix this issue, change the following line in web.xml

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

to

<listener-class>com.liferay.portal.kernel.spring.context.PortletContextLoaderListener</listener-class>
