Actual

Using Kotlin 1.4.32 and Jackson 2.13.2.20220324 with jackson-module-kotlin I’m getting an exception

Caused by: java.lang.NoSuchMethodError: 'boolean kotlin.reflect.KClass.isValue()'

The same code works fine with Jackson 2.13.1

The regression is introduced in https://github.com/FasterXML/jackson-module-kotlin/pull/527 kotlin.reflect.KClass.isValue() was added in Kotlin 1.5 and not available in 1.4: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.reflect/-k-class/is-value.html

Expected

• get Kotlin 1.4 support back (the last release of 1.4 was not that long time ago to consider it end of life https://github.com/JetBrains/kotlin/releases/tag/v1.4.32) or
• explicitly state which versions of kotlin are supported by this module and that Kotlin 1.4 got dropped in 2.13.2. Jackson Kotlin Module’s release notes are stating: “No changes since 2.13.1?” for 2.13.2.
