----------------------------------------------
Thanks Ashu and Appy
I was on festival vacation, So didn't check this further.
V3 looks good. Can you also add the failure scenario in test
case(DummyReplicator can throw exception). This can cover the scenarios when
entry from entryLists should not be removed and retried.
Initially I observed the index problem during my code review and during
simulation of the same, I was printing the index returned from the future like
below code
{code}
int i = (int)f.get();
entryLists.remove(i);
{code}
Since I was assigning as int , so thats the reason, I got
IndexOutOfBoundsException. But as [~ashu210890] pointed out, before index
problem, the other problem of removal exists.
Thanks for looking into this
