Summary

Remove the restriction in java.time.Year.parse() method which requires the argument to have at least 4 digits.

java.time.Year.parse(CharSequence) method requires the argument to have at least four digits. For example,

Year.parse("200")

is currently throwing a DateTimeParseException. To parse year 200 correctly, the argument needs zero paddings, ie., "0200".

Make the parsing more lenient. It should accept years without leading zeroes.

Remove the following sentence in the method description of java.time.Year.parse().

Years outside the range 0000 to 9999 must be prefixed by the plus or minus symbol.
