[6.8] Incorrect week based parsing with java.time #58602
Description
related to this bug #41670 and fixed in v7.6+ PR fix #48349
affecting 6.8
week based dates are parsed in java.time with Sunday,1 calendar data rule. We cannot change this with java.locale.providers as that flag allows using SPI since jdk9+ (jdk8 is supported in 6.8)
reproduce
curl --request PUT \
--url http://localhost:9200/test \
--header 'authorization: Basic ZWxhc3RpYzpwYXNzd29yZA==' \
--header 'content-type: application/json' \
--data '{
"mappings" :{
"properties": {
"timestamp": {
"type": "date",
"format":"YYYY-ww",
"store": true
}
}
}
}'
curl --request POST \
--url http://localhost:9200/test/_doc \
--header 'authorization: Basic ZWxhc3RpYzpwYXNzd29yZA==' \
--header 'content-type: application/json' \
--data '{
"timestamp": "2020-33"
}'
results in
{
"error": {
"root_cause": [
{
"type": "mapper_parsing_exception",
"reason": "failed to parse field [timestamp] of type [date] in document with id 'Q9-p5XIBy0lAoBkyOJdN'"
}
],
"type": "mapper_parsing_exception",
"reason": "failed to parse field [timestamp] of type [date] in document with id 'Q9-p5XIBy0lAoBkyOJdN'",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "temporal accessor [{WeekBasedYear[WeekFields[SUNDAY,1]]=2020, WeekOfWeekBasedYear[WeekFields[SUNDAY,1]]=33},ISO] cannot be converted to zoned date time"
}
},
"status": 400
}
and since 7.6 it returns fine.
then when searching
curl --request GET \
--url http://localhost:9200/test/_search \
--header 'authorization: Basic ZWxhc3RpYzpwYXNzd29yZA==' \
--header 'content-type: application/json' \
--data '{
"stored_fields": [ "timestamp" ]
}'
correct
