[rules-users] Missing mvel class after upgrade 4.0.4 => 4.0.5

[Christian Gorbach]

hi ,

I am using maven, I tried to upgrade to the latest release be just 
changing the dools pom version number to 4.0.5
After the upgrade execution fails with the following stack trace:

...

has anyone successfully switched to the latest version using the maven2 
poms?
thanks in advance,
