Could anyone explain why this works

val longs = List(100) { random.nextLong(6868L) }
assertThat(longs.all { it < 6869L }).isTrue()

But when I use property access syntax for

isTrue

it throws

Cannot infer type parameter SELF in val <SELF : AbstractBooleanAssert<SELF!>!> AbstractBooleanAssert<SELF>.isTrue: SELF!

val longs = List(100) { random.nextLong(6868L) }
assertThat(longs.all { it < 6869L }).isTrue

I'm using assertJ. Just wondering if this is kotlin or assertj issue.

🤔

class AssertJTest {
    @Test
    fun asas1() {
        val longs = List(100) { Random.nextLong(6868L) }
        Assertions.assertThat(longs.all { it < 6869L }).isTrue()
    }

    @Test
    fun asas2() {
        val longs = List(100) { Random.nextLong(6868L) }
        Assertions.assertThat(longs.all { it < 6869L }).isTrue
    }
}

Could be an issue? When I'm looking into the bytecode, both will generate the same.
