TIBCO Spotfire Server fails to start with exception "More than one fragment with the name [spring_web] was found. This is not legal with relative ordering" in catalina.log file.

TIBCO Spotfire Server may fail to start with the following error in both server.log and catalina log file when there are multiple versions of spring-web.jar files deployed in Spotfire. This error is specific to spring-web.jar but similar errors can be seen if you have duplicate jar files.

In this example, spring-web.jar was placed in both <server installation dir>/tomcat/custom-ext and <server installation dir>/tomcat/webapps/spotfire/WEB-INF/lib folders, where as it supposed to be deployed only in "<server installation dir>/tomcat/webapps/spotfire/WEB-INF/lib" folder

Please note that custom JAR files needs to be placed in "<server installation dir>/tomcat/custom-ext".
