for any reason, such as a garbage collection or other background activity, two or more executions will occur quickly and continuously, allowing subsequent executions to "catch up". In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming that the system clock relied on by object.wait (long) is accurate).Fixed rate execution applies to repetitive execution activities that are sensitive to absolute time, such as hourly timekeeping, or running sc
