DateFieldMapper ignore_malformed misses java.lang.ArithmeticException

[iverase]

It seems when parsing dates as longs, we can have arithmetic exceptions. Steps to reproduce:

PUT test01
{
  "mappings": {
    "properties": {
      "dadate": {
        "type": "date",
        "ignore_malformed": true
      }
    }
  }
}
     
PUT test01/_doc/1
{
  "dadate": "-522000000"
}

The error in the logs looks like:

Caused by: java.lang.ArithmeticException: long overflow

Hi, i was having a similiar issue (#52396 (comment)). In cases when the long is 10 digits or shorter it isn't parsed as epoch milliseconds, but to a year
