StackOverflowError while debugging reflect.internal.Importers

    Details

    • Type: Bug
    • Status: Open
    • Priority: Major
    • Resolution: Unresolved
    • Affects Version/s: Scala 2.11.1
    • Fix Version/s: None
    • Component/s: Compiler (Misc)
    • Labels:
      None
    • Environment:

      Scala IDE in Debug mode

      Description

      I got some StackOverflowErrors while debugging reflect.internal.Importers#importSymbol, but I'm not sure if they occurred because of this file or because I tried to view the contents of the symbol passed to the method importSymbol. This is not the first time that such StackOverflowErrors occurred but they occur only intermittently, thus it is difficult to find out what is the reason for them.
