In jython scripting how to exit if a condition is not met without using sys.exit()

In the import scipt in FDMEE if a particular condition is not met after giving the loginfo that the condition is not met,the query should not move forward. If sys.exit() is put then it gives an unsuccessful in teh process details and also in the log file says FATAl error. Is there any other way to exit from the sytem.
