Update Manager 6.5 issue ""interface com.vmware.vim.binding.integrity.VcIntegrity is not visible from class loader""

This post is related to the issue what we faced today when we replaced the SSL certificates in our setup. 

When I launched the web-client and access the update manager tab,  I get the message  "interface com.vmware.vim.binding.integrity.VcIntegrity is not visible from class loader"

I started off by restarting the VMWare vSphere Update Manager Service for the affected vCSA:

1. Log into vCenter using the administrator@vsphere.local account.
2. Home - System Configuration - Services - Restart

This did not resolve my issue... And we tried restarting all the services by SSH/Console into the affected server and run the following commands:

service-control --stop --all
service-control --start --all
Still no luck. 

Make sure the certs are applied and it gets reflected in the config file. ( verify if the thumbprint matches) 

root@homelab71 [ /usr/lib/vmware-updatemgr/bin ]# pwd

root@homelab71 [ /usr/lib/vmware-updatemgr/bin ]# ./updatemgr-util config -g | less


 Connect to the vCenter Server using SSH and run the following commands:

Re-try to replace the SSL certificates.

/usr/lib/vmware-updatemgr/bin/updatemgr-util refresh-certs
/usr/lib/vmware-updatemgr/bin/updatemgr-util register-vc
service-control --start vmware-updatemgr

Logout and login to the WebClient again. 

Verify that VMware Update Manager is accessible in the vSphere Web Client.
