Exception is logged when Java VM is shutting down.

Reproduction Steps

Kotlin unit test synthesizing an empty app:

import software.amazon.awscdk.core.App
import kotlin.test.Test
import kotlin.test.assertEquals

class AssemblyTest {
    @Test fun testSynthesize() {
        val app = App()
        val cloudAssembly = app.synth()
        assertEquals(0, cloudAssembly.stacks.size)
    }
}

What did you expect to happen?

No stacktrace logged.

Same issue, and same result as @timmattison. Also, it appears intermittently. The Stack does get built and deployed successfully.

[michaelbrewer]

Very strange issue

I started receiving this today, it appears to run when maven runs tests.

Hey! Thanks for reporting! It appears the de-registering method cannot be called during VM shutdown, causing this stack trace to be logged. It should not affect your application's ability to run correctly and can be ignored until we release an updated version of the runtime which no longer attempts the illegal operation.
