A DESCRIPTION OF THE PROBLEM :
In appendPattern​(String pattern) method, following pattern letters/builder mappings are presented:
Pattern Count Equivalent builder methods
uu 2 appendValueReduced(ChronoField.YEAR, 2, 2000)
yy 2 appendValueReduced(ChronoField.YEAR_OF_ERA, 2, 2000)
The problem is there is no appendValueReduced method which takes 3 parameters. I guess one of them is missing here.
