Exception in argument-list-wrapping

[mklnwt]

Upgrading from 1.1.0 to 1.1.1 result in an exception for the following case:

fun Foo.map(): List<String> = listOf(
    1,
) + listOf(2).map { it }

Rule 'standard:argument-list-wrapping' throws exception in file 'Foo.kt' at position (1:37)

Note: this is a simplified example

Your Environment

I was able to reproduce it on main with a test.

@Test
fun `Unexpected exception`() {
    val code =
        """
        fun Foo.map(): List<String> = listOf(
            1,
        ) + listOf(2).map { it }
        """.trimIndent()
    argumentListWrappingRuleAssertThat(code)
        .hasNoLintViolations()
}

Note: this is a simplified example

Yeah, I love simplified example that exposes problems. That is easy to work with.

This is not a regression bug of the 1.1.x releases. It will be fixed in 1.2.

I was able to reproduce it on main with a test.

@Test
fun `Unexpected exception`() {
    val code =
        """
        fun Foo.map(): List<String> = listOf(
            1,
        ) + listOf(2).map { it }
        """.trimIndent()
    argumentListWrappingRuleAssertThat(code)
        .hasNoLintViolations()
}

Hello, I have an issue #2682 which is also about rule argument-list-wrapping, can I ask you how to write a test like this?
