Update to SLF4J to version 2.0.x

[devurandom]

Version 2.0.7 of SLF4J was released: https://www.slf4j.org/news.html

The latest released version of HikariCP, version 5.0.1, depends, for Java 11 and newer, on slf4j-api version 2.0.0-alpha1:
https://github.com/brettwooldridge/HikariCP/blob/HikariCP-5.0.1/pom.xml#L555-L566

Since mixing 2.0.x and 1.7.x slf4j-api versions is not supported (cf. https://www.slf4j.org/faq.html#changesInVersion200), it would be nice if HikariCP could update to a current, stable version of SLF4J.

slf4j 2.x provides explicitly modularized jar files, and they also claim that v2 should be a drop in replacement for 1.x.

Is the reason that this ticket was closed to avoid causing chaos downstream?

Asking because I'm working on converting automatic jars to explicitly modularized ones, and I'm considering just excluding hikari's dependency on slf4j-api:1.x in favor of 2.x, and I'm curious to know if there is some technical reason why hikari does not depend on the newer versions.

• I am seeing the same issue at When JDBC Driver enables transactions and auto-commit, multi-threaded deletion will fail ClickHouse/clickhouse-java#2023 . com.clickhouse:clickhouse-jdbc:0.7.1-patch1 is using a newer version of org.slf4j:slf4j-api:2.0.7 which is causing a dependency conflict.
