Hey Gábor, Thanks for chiming in here. Are there any projects in particular that you're concerned about? Moving first to JDK11 also works for me, but I really think we should drop Java 8 since we've released 1.16.0.
Some related/dependent libraries: - Spark 4.x is JDK17/21 - Hive 4.0 is JDK8+ (march 2024), Hive 4.1.x is JDK17+ (July 2025), Hive 4.2.x is JDK21+ (not yet released) - Iceberg 1.10.0 is JDK11+, and JDK8 has been dropped <https://github.com/apache/iceberg/pull/10518> since 1.7.0. - Flink 2.0 is JDK17+ <https://nightlies.apache.org/flink/flink-docs-release-2.1/docs/deployment/java_compatibility/> - Hadoop 3.4 is still Java 8. So some libraries are still JDK11. I've prepared a PR to bump to JDK11: https://github.com/apache/parquet-java/pull/3314 Kind regards, Fokko Op di 16 sep 2025 om 11:38 schreef Gábor Szádovszky <ga...@apache.org>: > parquet-java is quite low in the dependency stack of many systems.
