[toolbox] Cannot invoke Java vararg constructor

[Jerzy Muller]

When I try to invoke Java vararg constructor in toolbox typecheck fails - it needs Array[T] to be passed as an argument:

scala> toolbox.typecheck(toolbox.parse("new debug.JavaVarArg(1)"))
scala.tools.reflect.ToolBoxError: reflective typecheck has failed: type mismatch;
 found : Int(1)
 required: Array[Integer]

Standard methods taking varargs works ok:

scala> toolbox.typecheck(toolbox.parse("java.util.Arrays.asList(1,2,3)"))
res2: toolbox.u.Tree = java.util.Arrays.asList[Int](1, 2, 3)

I logged Jira for it here: https://issues.scala-lang.org/browse/SI-9212
