Gaurav, Restarting the server flushes the cache inside eclipselink and hence next time the list is retrieved (once server is restarted) it will get a new copy the pojo with an new one to many relationship. In hibernate you can flush the cache with primary key and the pojo object class, but it becomes a real pain as systems get more complicated to track where these flushes are required.
Its not really worth spending any time on this, the design needs modifying, which I could do if there are no objections. Cheers Greg.
