com.liferay.taglib.aui; version="7.3.0" <com.liferay.util.taglib_2.9.0 [552]>
com.liferay.taglib.portlet; version="7.1.0" <com.liferay.util.taglib_2.9.0 [552]>

org.eclipse.core.runtime; version="2.0.0" <com.liferay.portal.osgi.web.wab.extender_2.0.18 [13]>

Possible workarounds: 

1.) Uninstall portlet via gogo shell before tomcat restart

2.) Add some .jsp file and spring-context.xml to WEB-INF - attachment sample-spring-mvc-freemarker-portlet-1.0-SNAPSHOT-with-jsp-and-spring-xml.war

3.) Rebuild portlet and redeploy (after restart its now working again)
