subject [contrib #482] OOME when parsing expression inside XML
code 
Got the following exception when trying to save a file containing this fragment of code:

object test {
  class Game {
    var players: List[Player] = _
    
    def toXml = <game><players>{players.map(_.toXml)}</players><game>
  }
  
  class Player {
    def toXml = <player/>
  }
}

Have no idea why this was assigned to me.

The original contribution was for the eclipse plugin. I changed this in the BTS but I left it for Burak. I hope he knows better what's happening

Sean wrote: If its a matter of a fix not being propagated into the Plugin yet, that will happen in the next release. It doesn't need to be reported as a bug on the plugin... But neither 2.5.0-RC2 nor current checkout (r11109) scalac crash on that. Although they report error in XML literal. If the game tag is properly closed they compile it ok. Maybe the author deleted the / when he was substituting < with &lt;

it's a matter of plug-in not being in sync, this is a dupe of the bug that got fixed last week.
