Exception with Timbre v6.3.1

[dharrigan]

Hi,

Clojure CLI version 1.11.1.1435

openjdk 21.0.1 2023-10-17 LTS
OpenJDK Runtime Environment Temurin-21.0.1+12 (build 21.0.1+12-LTS)
OpenJDK 64-Bit Server VM Temurin-21.0.1+12 (build 21.0.1+12-LTS, mixed mode, sharing)

com.fzakaria/slf4j-timbre {:mvn/version "0.4.1"}
com.taoensso/timbre {:mvn/version "6.3.1"}

When starting an application using these dependencies, the following is thrown:

Reverting to com.taoensso/timbre {:mvn/version "6.2.2"} does not produce an error.

Do let me know if you require any further information.

Thank you.

We're running into this as well when we try to upgrade Timbre.

@dharrigan @mike706574 Hi David, Mike - in case this is still relevant for you, you might want to try Timbre v6.6.0-RC1 which now includes built-in SLF4J(v2) support that'll always be automatically kept in-sync with the latest Timbre release.

Thank you, will do!
