VCSStreamMonitor input request. Cannot process event

Question

The class listed below is added to the VCSRunProcess.addErrorMonitor() method. In order for it to be called, I have to set VCSRunProcess.setInputData("Y"), which in turn sends "Y" regardless of choices made in the MessageDialog.
If I don't use VCSRunProcess.setInputData("Y"), the process will hang until a timeout occurs.
  private static class VSSInputMonitor extends VCSStreamMonitor {
    private String sError = new String();
    protected void patternMatched( RunProcess rp )  {
      try {
        String sInputData = ( MessageDialog.confirm( Ide.getMainWindow() , sError , "VSS Input", null) ? "Y" : "N");
        rp.log(sInputData);
        VCSProcessUtils.sendInputData( rp.getStarter().getProcess(), sInputData, true );
      } catch (IOException ex)  {
        ExceptionDialog.showExceptionDialog( Ide.getMainWindow(), ex );
    protected void streamLine(String sOutput, RunProcess rp)  {
      sError += sOutput;
      patternMatched(rp);
  }When the MessageDialog has finished, an IOException is thrown stating the following stack-trace:
java.io.IOException: The system cannot find the path specified.

I'm afraid I can't really provide much guidance here. I spoke to PaulB (developer responsible for these APIs) and he could not think of a good reason why you're having these problems... It's perhaps something specific to ss.exe.
FWIW, the SourceSafe integration we're implementing for 10.1.3 doesn't go via the command line (it uses OLE instead), so it doesn't have these problems... this is why I can't be as helpful as I'd like to be. I tried writing a SourceSafe extension based around SS.EXE a while back, and quickly came to the conclusion that Microsoft decided to write SS.EXE in a way that made it very difficult to integrate into other products as a command line tool.
