   Preondition Violations
   Expression super.testUnixLineSeparator() is a method call throwing exception(s) that should be caught by a try block that will be extracted
   Expression currentValue.setTime(fmt.parse(currentStringValue)) is a method call throwing exception(s) that should be caught by a try block that will be extracted
   Expression super.testUnixLineSeparator() is a void method call, and thus it cannot be parameterized
   Expression currentValue.setTime(fmt.parse(currentStringValue)) is a void method call, and thus it cannot be parameterized
