xxcopy single file copy in Java fails with double spaces in filename

I'm using xxcopy to do single file copies in a Java program.  All is well, unless the filename contains two consecutive spaces.

cmd /c xxcopy  "c:\source\folderx\file  name.doc" "c:\dest\foldery\"  /VL /C /H /K /YY /Q3

The code looks something like this, where sExec is the string above:
            Process p = Runtime.getRuntime().exec(sExec);
            iRtn = p.exitValue();

I'm outputting the exact value of "sExec", and then copying it into Start/Run.  It runs successfully from Start/Run.  Does anyone understand why this same command fails when run from a Java program?
