             Fix For: 5.1.1.CR1, 5.1.1.FINAL


Hi,
I'm trying to migrate my application to Infinispan 5.1.0.FINAL but I have some problem.
 
My code uses put method passing lifespan parameter. In the new Infinispan version it seems that if I put an entry to the cache with a lifespan (e.g. 10 seconds) and then, after 5 seconds, I put the same entry with lifespan = 10 seconds, the lifespan is not overrided and the cache entry expires after 10 seconds from the first operation.
 
Here an example of code that reproduces the problem:
 
        final Cache cache = .... // Obtain cache instance
       
        // Put entry in cache
        cache.put( "key_001", "v_001", 10, TimeUnit.SECONDS );
 
        int x = 0;
        while ( true ) {
            // print cache entry every 500ms
            System.out.println( ( x++ * 500 ) + "--->" + cache.get( "key_001" ) );
 
            // every 5 seconds put the same entry with lifespan = 10 seconds
            if ( x % 10 == 0 ) {
                System.out.println("PING");
                cache.put( "key_001", "v_001", 10, TimeUnit.SECONDS );
            }
            Thread.sleep( 500 );
        }
 
The results is:
0--->v_001
500--->v_001
1000--->v_001
1500--->v_001
2000--->v_001
2500--->v_001
3000--->v_001
3500--->v_001

16000--->v_001
16500--->v_001
17000--->v_001
17500--->v_001
 
With Infinispan 5.0.1 the result is
0--->v_001
500--->v_001
1000--->v_001
1500--->v_001
2000--->v_001
