[Java] Error generating java due to a default for a date #5086 (#5333)

Browse Source 
* Fix OpenAPITools#5086 handling date examples in openapi 3.0

* Fix OpenAPITools#5086
created test for handling date value
renamed variable p to schema
created field birthday in test yaml

* Fix OpenAPITools#5086
reverted birthday, because breaking tests

* Fix OpenAPITools#5086
create String in ISO format for date default. That can be converted to LocalDate
fixed Test
