Kotlin 1.9.23
JDK 21
Mockito 5.7.0

I have jUnit test:

val mockOperation: () -> GetAllOrganizationsResponse = Mockito.mock()

@Test
fun testGetOrganizations() {
    val request =
        GetAllOrganizationsRequest.newBuilder()
    request.setSearchCriteria(
        SearchCriteria.newBuilder()
            .setValue(StringValue.of(IDENT))            
    )
    val req = request.build()

    grpcClient.getOrganizations(IDENT)

    Mockito.verify(grpcWrapper).invokeGrpcCall("getOrganizations", req.toString()) { mockOperation() }
}

And this verify is failing. Because there is a difference in expected and actual value for request. And the difference is an empty row 🙁

Expected result:

GrpcWrapper#0 bean.invokeGrpcCall(
    "getOrganizations",
    ["searchCriteria {
  value {
    value: "12345678"
  }
}
"],
    () () -> GetAllOrganizationsResponse?
);

Actual result is:

GrpcWrapper#0 bean.invokeGrpcCall(
    "getOrganizations",
    ["searchCriteria {
  value {
    value: "12345678"
  }
}
"],
    () () -> GetAllOrganizationsResponse?
);
                                           <-- empty row     

And this is quite unhappy.
Why is an empty row there ?
How to avoid it ?
How to tell Mockito.verify to ignore empty line ?
