ParquetWriter is incompatible with JDK25

まず、スタックトレースに示されているテストで ParquetWriterTest.kt の失敗を再現し、次に HadoopOutputFile.fromPath と Hadoop UserGroupInformation を経由して ParquetWriter.kt:75 を追跡します。JDK25 との互換性に必要なプロジェクト側の変更を特定し、JDK25 で parquet 書き込みテストが getSubject 例外なしに完了することを確認します。

Describe the bug, including details regarding any error messages, version, and platform.

Hello, I'm trying to upgrade my code base to JDK25 and I'm having this issue on my tests

It appears this is an issue within the Hadoop libraries upon which Parquet Java depends on
