Using Scala array from java

I'm trying to use some library code written in scala from a java program. I have a function that returns an Array (a scala Array) and I thought it would be possible to do

Tree[] = ScalaObject.myScalaFunction()

But the I get this error : 

[error] found   : scala.runtime.BoxedArray
[error] required: org.grammaticalframework.Trees.Absyn.Tree[]

What is the correct way to use a scala array in java ?

With 2.7, you should be able to

Tree[] t = (Tree)ScalaObject.myScalaFunction().unbox(Tree.class);

in Java.

With 2.8, it will work as you hoped it would.
