Not able to launch traffic configuration form

NNM 10.40 with latest patch installed

Master collector installed on NNM server and started fine, no issues observed in boot.log or jbossserver.log

Leaf collector installed on different server and started fine, no issues observed in boot.log or jbossserver.log

Launching Traffic configuration form from NNM and it presents me blank page.

Checked ports 12080 and 12043 are running fine for master collector.

I see below error in jbossServer.log when launching traffic configuration form,

ERROR [org.apache.catalina.connector.CoyoteAdapter] (tomcat-exec-4) An exception or error occurred in the container during the request processing: java.lang.AbstractMethodError: com.hp.ov.nms.as.ejb.NmsWebRealmSettingsImpl.isBannerEnabled()Z
at com.hp.ov.nms.as.server.tomcat.AbstractWebAuthenticator.shouldCheckBanner(AbstractWebAuthenticator.java:212)

Please advise to solve this problem, as usual Micro Focus NNM support is pathetic.
