Needs Java 19 support for minimize()

[Jire]

Error Unsupported class file major version 63

When using Gradle toolchains via Kotlin extension:

kotlin {
    jvmToolchain {
        languageVersion.set(JavaLanguageVersion.of(19))
    }
}

With latest Kotlin 1.8.0 (and 1.8.0-RC2)

Only an issue when using minimize()

This seems to be on main already. I vote for a release :-)

Not sure if I should create a separate issue, but I also run into Unsupported class file major version 63 when I try to run my build with JDK 19, even without minimize()

org.gradle.api.GradleException: Could not add file '...' to ZIP '...jar'.

Would it be possible to create a new release with 404c7c2 included? (Or maybe already upgrade to 9.4 and release that, since meanwhile there is another ASM release? I created #817, hope it's not already included somewhere and I caught it right...)
