When deleting a repeating event using "All Following", you get a java.text.ParseException in the console. The repeating event gets deleted but you are unable to create another repeating event.

1. Create a Repeating Event
2. Delete the Repeating Event using "All Following"
3. You will get an exception stacktrace
4. Try to create another Repeating Event and save. Event does not save and you get the same exceptions

PASSED Manual Testing using the following steps:

1. Create a few Repeating Events with a Daily, Monthly, Weekly, and Yearly repeat cycle and no end date
2. Delete the Repeating Events using "All Following"
3. Assert that no errors display on the console
4. Create a few Repeating Events with a Daily, Monthly, Weekly, and Yearly repeat cycle and specify an end date
5. Delete the Repeating Events using "All Following"
6. Assert that no errors display on the console
7. Create a few Repeating Events with a Daily, Monthly, Weekly, and Yearly repeat cycle and specify a specific number of occurrences
8. Delete the Repeating Events using "All Following"
9. Assert that no errors display on the console

Fixed on:
Tomcat 7.0 + MySQL 5. Portal 6.2.x GIT ID: a4076e2b170d4b627bea9a95399cb0f955501c57.
Plugins 6.2.x GIT ID: 6afa94b9c21a8f46bd8a955bd43afe6b8b93bf4b.

After deleting several repeating events, whether it is daily, weekly, monthly, and yearly, and with different end dates and different number of occurrences, the user will not be able to see a ParseException in the console.
