Expected Behavior

> Task :detekt FAILED
exceptions - 20min debt
        SwallowedException - [f] at src\main\kotlin\test.kt:4:4
        SwallowedException - [f] at src\main\kotlin\test.kt:7:4

Observed Behavior

> Task :detekt FAILED
exceptions - 20min debt
        SwallowedException - [f] at src\main\kotlin\test.kt:4:4

Steps to Reproduce

fun f() {
	try {
		println("verifySomething")
	} catch (ex: AssertionError) {
		try {
			println("verifySomethingElse")
		} catch (ex2: AssertionError) {
			throw ex.initCause(ex2)
		}
	}
}

Context

No context, just noticed it. See usage at https://github.com/TWiStErRob/net.twisterrob.cinema/blob/master/Heroku/backend/network/src/test/kotlin/net/twisterrob/ktor/client/ConfigureLoggingTest.kt#L212-L220
The nested AssertionError is guaranteed after "noMore" throwing.

Your Environment

• Version of detekt used: io.gitlab.arturbosch.detekt:detekt-gradle-plugin:1.18.1
• Version of Gradle used (if applicable): 6.9
• Gradle scan link (add --scan option when running the gradle task): -
• Operating System and version: Windows 10
• Link to your project (if it's a public repository):
  https://github.com/TWiStErRob/net.twisterrob.cinema/blob/master/Heroku/backend/network/src/test/kotlin/net/twisterrob/ktor/client/ConfigureLoggingTest.kt#L212-L220 but Detekt integration is not merged yet.

Since throw ex.initCause(ex2) refers ex2, I think the observed behavior is correct because ex2 is not swallowed.

[BraisGabin]

I agree with chao that this doesn't seem a ShallowedException. But I think that we are missing a super call in this rule. And it could generate the described problem. I just notice it reading #4158. We could add a test to ensure this.
