Calling JAR file hangs Process

[Wheaties]

.NET version: 2.0
Platform: Windows XP, SP2
Compiler: VS2005

Problem:

I call a JAR file using a Process by first passing in a ProcessInfo object. The JAR file runs successfully, however, the java.exe process does not terminate even when consuming ~0 CPU cycles. Hence a call to Process::waitForExit() hangs my program. Anyone run into this sort of problem?

Code:

            ProcessStartInfo AcSPInfo = new ProcessStartInfo("\"C:\\Program Files\\Java\\jre1.6.0_07\\bin\\java.exe\"", 
                                                         " -jar C:\\Workspace\\Scratch\\AcSP.jar");

            AcSPInfo.WorkingDirectory = "C:\\Workspace\\Scratch";
            AcSPInfo.RedirectStandardError = false;
            AcSPInfo.RedirectStandardInput = false;
            AcSPInfo.RedirectStandardOutput = true;
            AcSPInfo.CreateNoWindow = true;
            AcSPInfo.UseShellExecute = false;

            Process AcSP = new Process();

            AcSP.StartInfo = AcSPInfo;

            try
            {
                    AcSP.Start();
                    StreamReader output = AcSP.StandardOutput;
                    AcSP.WaitForExit(); //la la la, when will you finish!?
                    Console.Out.Write(output.ReadToEnd());
            }
            catch (Exception e)
            {
                    Console.Out.WriteLine(e.Message);
            }
