When classes are loaded, the number of classes newly loaded during this dialog step is recorded for both the local and the shared class pools (Count local/shared). If two VMs load the same class at about the same time, the second VM cannot store the class in the shared class pool, as the first VM has already done so. This situation is referred to as a class loading conflict (Count conflict). Both allocated and freed memory is stored in the statistic record (Memory allocated/freed local/shared).
