For those using the Gradle Kotlin DSL, I was able to invoke the formatter without issues with JDK 17 by doing the following:

tasks.register<JavaExec>("ktlintFormat") {
    group = "formatting"
    description = "Fix Kotlin code style deviations"
    classpath = ktlint
    mainClass.set("com.pinterest.ktlint.Main")
    args("-F", "src/**/*.kt")
    jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")
}

The most important part here is adding:

jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")

I think this bug is still not fixed. In case the linter has to fix some linting issues there is still an exception module java.base does not "opens java.lang" to unnamed module.

For maven projects using the maven-antrun-plugin you can add this to your pom:

<java taskname="ktlint" dir="${basedir}" fork="true" failonerror="true" classname="com.pinterest.ktlint.Main" classpathref="maven.plugin.classpath">
      <jvmarg value="--add-opens"/>
      <jvmarg value="java.base/java.lang=ALL-UNNAMED"/>

It worked for me by adding the following line to .mvn/jvm.config --add-opens java.base/java.lang=ALL-UNNAMED

I have the same version combination and the same failure happens.

You could try to run KtLint with --add-opens "java.base/java.util=ALL-UNNAMED" --add-exports="java.base/sun.nio.ch=ALL-UNNAMED" arguments.
