How to create a scala.collection.immutable.Seq from a Java List in Java?

The akka Java documentation for routers as well as the ScalaDoc for CyclicIterator both suggest that the CyclicIterator constructor takes a List.

You can use scala.collection.JavaConversions.asScalaBuffer to convert the Java List to a Scala Buffer, which has a toList method, and a Scala List is a collection.immutable.Seq.

You can try this:

scala.collection.JavaConverters.asScalaIteratorConverter(list.iterator()).asScala().toSeq();
