Discovery issue incorrectly reports default methods in Kotlin interfaces

[hektorKS]

Hello 👋 I just tested 1.13.2 and DiscoveryIssueNotifier is flooding me with warnings for my Kotlin setup for contract testing (that works perfectly fine - there are no discovery issues). Is it possible to fix it too or provide possibility to disable this new discovery feature?

Pseudocode example:

interface DatabaseContract {
    val database: Database
    
    @Test
    fun `should save in batch`() {
        ...
    }

    @Test
    fun `should read all`() {
        ...
    }
}

class InMemoryDatabaseTest: DatabaseContract {
    override val database = InMemoryDatabase()
}

class PostgresDatabaseTest: DatabaseContract {
    override val database = PostgresDatabase()
}

@hektorKS Could you please share the output that is logged?

I tried to reproduce the issue with the following two Kotlin files, to no avail:

import org.junit.jupiter.api.Test

interface KotlinInterfaceTestCase {
    val data: Any?

    @Test
    fun test() {
    }
}

class KotlinInterfaceImplementationTestCase : KotlinInterfaceTestCase {
    override val data = "foo"
}

Thanks for quick response! I started digging why it works for you and not for me and looks like it was some caching problem, restarting gradle daemons helped.
