The Group Communication Service (jGCS) intends to provide a generic API for applications that need group communication primitives, such as virtual synchrony or atomic broadcast. It is a Java based common API to several toolkits such as Spread, Appia, and JGroups.
A new notification about when members are kicked from the group was added to the group communication. Some code maintenance was done. The javadoc was improved.
