Project groups with ampersand in name lose permissions after upgrade

I upgraded Continuum from 1.3.6 to 1.4.1
Some of my projets had ampersand in their name. In 1.3.X, this was allowed.

Now in 1.4.1, the interface block you from creating project with ampersand in their name. However, for every project with ampersand already in their name, those project are locked out.

When opening the project, the following message is displayed :
Authorization Error
You are not authorized to access this page. Please contact your administrator to be granted the appropriate permissions.

In the logs, the following trace is displayed:

 INFO  org.codehaus.plexus.redback.authorization.rbac.RbacAuthorizer  - no permission found for operation continuum-view-group resource Questions & Answers
