ParquetWriter is incompatible with JDK25

### 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

### Component(s)

_No response_

Beginne damit, den Fehler in ParquetWriterTest.kt bei dem im Stack Trace gezeigten Test zu reproduzieren, und verfolge dann ParquetWriter.kt:75 über HadoopOutputFile.fromPath und Hadoop UserGroupInformation weiter. Ermittle die seitens des Projekts erforderliche Änderung für die Kompatibilität mit JDK25 und überprüfe, dass der Test zum Schreiben von Parquet unter JDK25 ohne die getSubject-Ausnahme erfolgreich abgeschlossen wird.
