Description
Process: horse.haynet.debug, PID: 10367
java.lang.IllegalArgumentException: At most one variable-length numeric field in a row is allowed, but got several: [year, hourOfAmPm]. Parsing is undefined: for example, with variable-length month number and variable-length day of month, '111' can be parsed as Jan 11th or Nov 1st.

Example formatter:
format(
format = DateTimeComponents.Format {
monthName(MonthNames.ENGLISH_ABBREVIATED)
chars(" ")
day(Padding.NONE)
chars(" ")
year(Padding.ZERO)
amPmHour(Padding.NONE)
minute();
amPmMarker("am", "pm")
},
AFAIK, this is incorrect, or the error is wrong at minimum? As there are two variable lengths, day of month and amPmHour (as they are padding none), but year (should) expects 4 digits not 2-4.
Also in a formatting situation, I don't care about parsing, I'm formatting, so it would be really nice to skip the parser check when I'm only outputting. If parsing that date, 100% agree could potentially be wrong.
