DateTimeFormatter is used in static context, but not thread safe

DateTimeFormatter is used in static context but not thread safe, a formatter instance is created in PrimitiveStringifer.DateStringifier, and DateStringifier is created in static final DATE_STRINGIFIER, TIMESTAMP_MILLIS_STRINGIFIER, TIMESTAMP_MICROS_STRINGIFIER, TIMESTAMP_NANOS_STRINGIFIER, TIMESTAMP_MILLIS_UTC_STRINGIFIER, TIMESTAMP_MICROS_UTC_STRINGIFIER, and TIMESTAMP_NANOS_UTC_STRINGIFIER.

This causes exceptions like the following to be thrown from parquet-code:

java.lang.ArrayIndexOutOfBoundsException: Index 633 out of bounds for length 13

A simple solution would be to change those from static to non static values.

I can create a PR if the solution is ok by the maintainers of the library.

Commencez dans PrimitiveStringifier.DateStringifier, en particulier par les chemins de toFormattedString et stringify indiqués dans la trace de la pile, et examinez les sept instances statiques de stringifier nommées dans l’issue. Vérifiez l’échec lors d’un formatage concurrent et utilisez les tests pertinents du projet pour confirmer que l’utilisation partagée ne lève plus l’exception signalée.
