Failed to parse single digit hour and lowercase am-pm of day into Java 8 LocalTime

Question

When I try to run the following code:

LocalTime test = LocalTime.parse("8:00am", DateTimeFormatter.ofPattern("hh:mma"));

I get this:

Exception in thread "main" java.time.format.DateTimeParseException: Text '8:00am' could not be parsed at index 0

Any idea why this might be happening?
