slf4j-api version change from 1.7.x to 2.0.x between morphia 2.2.8 and 2.2.9 is a breaking change

Describe the bug Morphia 2.2.9 updates slf4j-api from 1.7.x to 2.0.x which breaks downstream consumers that have slf4j implementation targeting 1.7.x.

To Reproduce

1. Create simple project with dev.morphia.morphia:morphia-core:2.2.9 and ch.qos.logback:logback-classic:1.2.11 in dependencies and try log anything.

// settings.gradle.kts
rootProject.name = "morphia-slf4j"
dependencyResolutionManagement {
  repositories.mavenCentral()
}

// build.gradle.kts
plugins { java; application }
application { mainClass.set("Main") }
dependencies {
  implementation("dev.morphia.morphia:morphia-core:2.2.9")
  implementation("ch.qos.logback:logback-classic:1.2.11")
}

// src/main/java/Main.java
public class Main {
    public static void main(String[] args) {
        org.slf4j.LoggerFactory.getLogger(Main.class).info("ok");
    }
}

1. Run gradle run
2. You get following message:

SLF4J: No SLF4J providers were found.
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#noProviders for further details.
SLF4J: Class path contains SLF4J bindings targeting slf4j-api versions prior to 1.8.
SLF4J: Ignoring binding found at [jar:file:/home/gross/.gradle/caches/modules-2/files-2.1/ch.qos.logback/logback-classic/1.2.11/4741689214e9d1e8408b206506cbe76d1c6a7d60/logback-classic-1.2.11.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#ignoredBindings for an explanation.

Expected behavior

Breaking change should at least be documented and avoided at the very least in patch release.

Yep. I’m on zulip. if your questions are purely morphia, though, perhaps use the discussions tab here.

I’ll roll it back. I’m about to cut a 2.2.10 release anyway which will, fingers crossed, be (one of?) the last releases of 2.2.x since 2.3 will soon be out.

If you’re using quarkus, have you seen https://github.com/quarkiverse/quarkus-morphia? There’s not a lot there yet but it works with quarkus and might be useful-ish. It will be better once 2.3 lands (and thus critter), though.
