This a placeholder for this issue. It is unlikely to be a problem in Scala IDE

When launching the following object in debug mode, Eclipse open a dialog stating that the class file does not contains any line number information (debug information).

package test

object NoDebugInfo {

  def main(args: Array[String]) {
    println();   // breakpoint here
  }
}

And this is true.
The companion class contains only the forwarder for the main method, and it has not line numbers for this method as it is a generated one.

The different actors in this chaine (compiler, vm, debugger) seems to do what is spec'ed, but the result is still this state.

I had a look through the specs and I didn't see how this could be handle differently.
