Bug? Error in Debug Mode, Release Mode runs fine

[Frederikson]

Hi,

don't know, if this really is a bug or some sort of misconfiguration of my system or just my fault. However, I thought it's better to post such things. If this is the wrong place to post this, I apologize.

Setup:
Windows 7 64 bit Professional.
Java JDK 7 for 32 bit

When I run a small example in Debug-Mode, I get error messages. When I run the example in Release mode, or from command line, everything is fine.

Example:

Sub Process_Globals
  Private reader As TextReader
End Sub

Sub AppStart (Args() As String)
  Dim sys As JavaObject
  sys.InitializeStatic("java.lang.System")
  reader.Initialize(sys.GetField("in"))
  Log("Enter name: ")
  Log("You have entered: " & ReadLine)
  Log("Enter family name: ")
  Dim f As String = ReadLine
  Log("Family: " & f)
End Sub

Sub ReadLine As String
  Return reader.ReadLine
End Sub

Log:

Enter name:
main._readline (java line: 82)

Silly me. I have overlooked that you've already written about the error in Debug-Mode.
Sorry for the unnecessary thread.

When I tested it it didn't work in release mode as well (which is expected as there is no external input stream).
