Spring 4.3.30 to Spring 5.3.18 - No thread-bound request found

Hello,

Attempting to upgrade Spring 4.3.30 to Spring 5.3.18. Get the following error when loading Tomcat 8.5.56:

Caused by: java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request.

Tech stack:
Eclipselink JPA 2.5.1
BasicDatasource connection is setup using Apache commons-dbcp-1.1
Apache CXF Bundle Jar 2.7.18.SP7-redhat-1 - used for JAXRS

I have tried to replace the RequestContextListener with an updated RequestContextFilter with default value for threadContextInheritable to true.

Listed below are some excerpts from web.xml, persistence.xml and spring-config.xml files. Any inputs will be useful.

Thanks,
Mansur Farooq`

Web.xml:

org.springframework.web.context.ContextLoaderListener

        <param-name>threadContextInheritable</param-name>
        <param-value>true</param-value>
