Missing breakpoint when enclosing class contains package name

[harpocrates]

Consider the following code:

package pkg1.other

class Mother {
  def greet = {
    println("hi mom")
  }
}

class Father {
  def greet = {
    println("hi dad")
  }
}

object Main extends App {
  val mom = new Mother 
  val dad = new Father 

  mom.greet
  dad.greet
}

Set a breakpoint at each of the println lines and then "debug" Main. Only the breakpoint in Father.greet actually works - breakpoint in Mother.greet is completely skipped!!!

It looks like if any of the enclosing packages (other in this case) is contained fully in a case-sensitive way in the class name (Mother in this case), the breakpoints inside of it get skipped.
