Kotlin data class and ArgumentMatchers issue

[johnowl]

When I run the test below (created only to illustrate a real problem) I expect it to pass, but it doesn't.

@JvmInline value class MyValueClass(
    val value: String,
)

class MyClass {
    fun myMethod(myValueClass: MyValueClass): String = myValueClass.value
}

class Test {
    @Test
    fun testDoSomething() {
        val myValueClass = MyValueClass("something")
        val mock = mock<MyClass>()

        whenever(mock.myMethod(eq(myValueClass))).thenReturn("something")

        assertThat(mock.myMethod(myValueClass)).isEqualTo("something")
    }
}

However, if I refactor the MyValueClass to be a data class, it works. Any workaround to make it work?

Dupe of #544 ?

See commit #545 which adds value class support for eq() matcher
