Signature verification failed error on open or edit a resource from Documentum

When I try to open/edit a resource from Documentum, I receive the following error:

signature verification failed: certificate for All-MB.jar.checksum not signed by a certification authority.

The problem is that the certificates from the Java Runtime Environment 1.6.0_22 or later no longer validate the signatures of the UCF jars.

Set the -Drequire.signed.ucf.jars=false parameter, as explained in the Setting a Parameter in the Launcher Configuration File / Startup Script topic.

-vmargs 
-Xms40m
-Xmx256m
-Drequire.signed.ucf.jars=false
