How to use untyped Java util. List to scala 2.8 buffer

I have to call some Java. Java that returns no type util. List. It seems that I can't convert it to scala 2.8 list without the compiler borking, and the following error occurs:

[INFO]  found   : java.util.List[?0] where type ?0
[INFO]  required: java.util.List[AnyRef]
[INFO]      val modules: Buffer[AnyRef] = asScalaBuffer(FeedEntry.getModules)

I tried normal

import scala.collection.JavaConversions._

val modules: Buffer[AnyRef] = FeedEntry.getModules

As clear

val modules: Buffer[AnyRef] = asScalaBuffer(FeedEntry.getModules)

I know the type of item in the list. I've tried to set it to the type of buffer, but I always get the same error

I look around, but all documents assume that I want to enter a Java list How to convert an untyped list?

Solution

I think you just need to make it the right type

val modules: Buffer[AnyRef] = 
  FeedEntry.getModules.asInstanceOf[java.util.List[AnyRef]]

Scala can get it from there and wrap it as a Scala collection by applying the implicit transformation of Java conversions
