Deprecation: False positive with Kotlin 1.4.0

[realdadfish]

After updating to Kotlin 1.4.0 Detekt reports me "Deprecation" on the following spots:

data class ByteArrayData(val data: ByteArray) {
    override fun equals(other: Any?): Boolean = when {
        this === other -> true
        javaClass != other?.javaClass -> false
        !data.contentEquals((other as ByteArrayData).data) -> false
              // ^^^^ Deprecation - [equals]
        else -> true
    }

    override fun hashCode(): Int = data.contentHashCode()
                                        // ^^^^ Deprecation - [hashCode]

    companion object {
        private val EMPTY = ByteArrayData(byteArrayOf())
        fun empty() = EMPTY
    }
}

Looking at 1.4.0's sources, I see that a couple of new methods have been added:

/**
 * Returns `true` if the two specified arrays are *structurally* equal to one another,
 * i.e. contain the same number of the same elements in the same order.
 * 
 * The elements are compared for equality with the [equals][Any.equals] function.
 * For floating point numbers it means that `NaN` is equal to itself and `-0.0` is not equal to `0.0`.
 */
@Deprecated("Use Kotlin compiler 1.4 to avoid deprecation warning.")
@SinceKotlin("1.1")
@DeprecatedSinceKotlin(hiddenSince = "1.4")
@kotlin.internal.InlineOnly
public actual inline infix fun ByteArray.contentEquals(other: ByteArray): Boolean {
    return this.contentEquals(other)
}

/**

 * i.e. contain the same number of the same elements in the same order.
 *

 */
@SinceKotlin("1.4")
@JvmName("contentEqualsNullable")
@kotlin.internal.InlineOnly
public actual inline infix fun ByteArray?.contentEquals(other: ByteArray?): Boolean {
    return java.util.Arrays.equals(this, other)
}

/**
 * Returns a hash code based on the contents of this array as if it is [List].
 */
@Deprecated("Use Kotlin compiler 1.4 to avoid deprecation warning.")
@SinceKotlin("1.1")
@DeprecatedSinceKotlin(hiddenSince = "1.4")
@kotlin.internal.InlineOnly
public actual inline fun ByteArray.contentHashCode(): Int {
    return this.contentHashCode()
}

/**

@SinceKotlin("1.4")
@JvmName("contentHashCodeNullable")
@kotlin.internal.InlineOnly
public actual inline fun ByteArray?.contentHashCode(): Int {
    return java.util.Arrays.hashCode(this)
}

When I look at the code with my IDE (AS 4.1-rc01) with Kotlin 1.4.0 plugin enabled, I don't see any warning. Also, Cmd-clicking on the method navigates me to the new (nullable-enabled) implementation.

This is with Detekt 1.10.0 with type resolution enabled (I still have my custom Android build, not rebased yet to master).

Hrm... thinking of it and looking at the implementation of the rule, this should probably be resolved with #2974, shouldn't it?

[arturbosch]

Yep, seems so. Please report after testing with 1.12.0-RC1 :)

I can confirm that this is gone with 1.12.0-RC1, thanks for the quick publishing!
