Re: [jgroups-users] Eclipselink cache coordination with JGroups in Docker in AWS

This is ok, as the UUIDs asociated with 120 are different. I assume the 
third entry left and later rejoined (as the first entry). However, on a 
new join, a node gets a different UUID but the IP address and port 
remains the same.

The reason the stale entry is still in the file is to minimize access to 
the backend store (e.g. S3), as some cloud stores charge for that.

See [1] for a detailed discussion of why this is the case, and how it 
can be changed if desired.
