With the current approch jusched is checking for the update when it is launched first time;

Test case
1.) install JRE 6u12 ( or any other 6u10 release)

2.) Check the Update schedule and make sure that current system time is lesser then the scheduled time.

3.) Set the UpdateServletURL to point to update loction

4.) launch the jusched and wait for some time

You will get the update notification. We can avoid this checking as first time who ever has installed may already have updated JRE. We should only check based on the schedule or else current time is greater then the scheduled time.
