Hi, has anybody seen this error when building native image containing ktor client ? I have tried different options by specific the offending class at build and runtime, but still having the same error.

Fatal error: com.oracle.graal.pointsto.util.AnalysisError$ParsingError: Error encountered while parsing io.ktor.client.engine.cio.CIOEngine.<init>(io.ktor.client.engine.cio.CIOEngineConfig)
Parsing context:

   at io.ktor.client.engine.cio.CIO.create(CIOCommon.kt:35)
   at io.ktor.client.HttpClientKt.HttpClient(HttpClient.kt:41)

The client is being pulled as a transitive dependency for rsocket-kotlin

nm.. the issued is fixed now by updating the latest GraalVMCE dev build and few other reflection configs.
