please update scala to newer latest version, this is been fixed in scala
Pekko is not even in the main part of the stacktrace. Scala and Play are much closer to the failure.
@He-Pin are you suggesting the issue is in scala.jdk.javaapi.FutureConverters$.asScala(FutureConverters.scala:73) ?
For reference, Pekko doesn't even use scala.jdk.javaapi.FutureConverters. It has its own FutureConverters class.
does look quite like scala/bug#12918
This is been fixed in scala
thanks sorted the issue
