pact-jvm: Exception using new consumer version selector method in kotlin

Hi,

I started to migrate the @Deprecated consumerVersionSelectors = [ ] in the @PactBroker annotation by the new way, using @PactBrokerConsumerVersionSelectors method like this. See bottom line:

However when running my PactTest that ran using commented-out code above, I get this exception:

I debugged a bit your library and figured, that this line tries to invoke the identified selectorsMethod with a testInstance param that is Optional.empty() though. I find it strange that invokeSelectorsMethod thinks my selector method has 1 param even though it doesn’t. This circumstance is explicitly handled in testClassHasSelectorsMethod:

• Kotlin version: 1.7.10
• Pact version: 4.3.13
• junit5: yes, PactVerificationInvocationContextProvider

What else I tried:

• Moving my selector method out of abstract class and into to concrete test class
• Making it “kotlin static” leads to not running into my breakpoint in testClassHasSelectorsMethod even, because its not contained in testClass?.kotlin?.members:

companion object {
        @PactBrokerConsumerVersionSelectors
        @JvmStatic
        fun consumerVersionSelectors(): SelectorBuilder = SelectorBuilder().branch("my-branch")
    }
