GC problems Ehcache where elements in the cache are eternal

[Mr. Vivek Srivastav]

I've declared a cache with elements in the cache as eternal & after a fixed interval I overwrite the cache with elements .

so my code looks like ,

Cache mycache = Cache("myCache",int maxElementsInMemory, boolean overflowToDisk, boolean eternal, long timeToLiveSeconds, long timeToIdleSeconds) ; //line 1

where maxElementsInMemory = 10000 , overflowToDisk = false , eternal =true , timeToLiveSeconds =0 , timeToIdleSeconds =0

so say at load time i get some data and add it to cache eg.

Isin isin = new Isin("US38259P5089") ; 
Element element = new Element(isin , isin ) ;  // line 2 
mycache.put(element); 

And after say 5 mins I again overwrite the data (again with same values hopefully ) .

//After 5 mins
Isin isin = new Isin("US38259P5089") ; 
Element element = new Element(isin , isin ) ;  // line 3 
mycache.put(element); 

So after 5 minutes after the execution of line 3 above does the previous element in the cache (made in line 2 ) get overwritten and so does it get eligible for garbage collection ?
