Using AGP 8.1:

fun testAutoVsCloseable(socket: LocalServerSocket) {
    val closeable: Closeable = socket
    val closeable2: AutoCloseable = socket
}

Lint should complain about both of these assignments (because the cast requires API level 28), but it only complains about the first one.

Marked as fixed.

Lint options:

    lintOptions {
        lintConfig = file('lint.xml')

        abortOnError true
        xmlReport true
        htmlReport true
        checkDependencies true
    }

Also, our project has custom lint rules. Failure happens with a dependency of 26.6.3 and 27.0.0.

Is any way to downgrade lint runner? This problem is keeping us from using AGP 4.0

Attached slightly different stacktrace for the same problem.

Wonder if disabling some lint rules could help to "fix" this problem, as it is also blocking for us 4.0 AGP upgrade.
