OpenJDK 13 requires -XX:+AllowRedefinitionToAddDeleteMethods flag

See original GitHub issue

OpenJDK 12.0.1 with even Kotlin 1.3.40-eap-67 works fine. However, using OpenJDK 13 build 23 I get the following exception:

Exception in thread "main" java.lang.RuntimeException: java.lang.UnsupportedOperationException: class redefinition failed: attempted to add a method

@abdullahumer sure:

    tasks.withType(Test).all {
        if (JavaVersion.current().isCompatibleWith(JavaVersion.VERSION_13)) {
            jvmArgs += [
                    "-XX:+AllowRedefinitionToAddDeleteMethods"
            ]
        }
    }
