Issue/Introduction

When attempting to install/upgrade to Ops Manager 2.10.27/2.10.28, the UI hangs on the  "Waiting for authentication system to start" page.

Checking /var/log/opsmanager/uaa.err shows the following error:

04-Feb-2022 13:47:18.807 SEVERE [main] org.apache.catalina.core.ApplicationContext.log Servlet.init() for servlet [spring] threw exception
	org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Failed to import bean definitions from relative location [spring/login-server-security.xml]

Offending resource: ServletContext resource [/WEB-INF/spring-servlet.xml]; nested exception is org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 14 in XML document from ServletContext resource [/WEB-INF/spring/login-server-security.xml] is invalid; nested exception is org.xml.sax.SAXParseException; lineNumber: 14; columnNumber: 97; cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'oauth:resource-server'.

The authentication system never starts, preventing the install/upgrade from completing.
