public voidfailingTestYearly1()
This test fails because of a bug in RecurrenceProcessor.expand(). We don't have time to fix the bug yet but we don't want to lose track of this test either. The "failing" prefix on the method name prevents this test from being run. Remove the "failing" prefix when the bug is fixed.
