A debugger problem?

There is a simple code from "Programming in Scala", chapter 7:

package multitable

object MultiTable {
def main(args: Array[String]) {
val multi = {
val table = for (i <- 1 to 10) yield {
val row = for (j <- 1 to 10) yield {
val prod = (i * j).toString
String.format("%4s", Array(prod))
}
row.mkString + "\n"
}
table.mkString
}

println(multi)
}
}

I placed a breakpoint at the line "String.format("%4s", Array(prod))"
Debugger does not stop on it. When I di dthe same thing in Eclipse plugin, it did stop. Is it a bug in IntelliJ IDEA plugin's debugger?

I tried the same thing in Netbeans Scala plugin. It didn't stop either, saying that there is no executable code at this line.... Ok, but how Eclipse manages to stop?
