Deployments can have user roles specified in their web.xml. These security roles are mapped to users/groups created in the application server.
For WebSphere this mapping has to be specified while deploying the deployable. Users and groups for WebSphere could be created while WebSphere is already started.
That results currently to situation when deployables are created and role mapping is specified while WebSphere is offline - roles are mapped to users and groups which doesn't exist at this moment (they are created after WebSphere is started). This can create inconsistencies resulting to users not being mapped to appropriate roles.
This improvement brings possibility to deploy deployables after WebSphere is started and users/groups are already created.
