Workaround for http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6468220

From cmd.exe /? output:

      If /C or /K is specified, then the remainder of the command line after
      the switch is processed as a command line, where the following logic is
      used to process quote (") characters:

      1.  If all of the following conditions are met, then quote characters
      on the command line are preserved:

      - no /S switch
      - exactly two quote characters
      - no special characters between the two quote characters,
      where special is one of: &<>()@ˆ|
      - there are one or more whitespace characters between the
      the two quote characters
      - the string between the two quote characters is the name
      of an executable file.

      2.  Otherwise, old behavior is to see if the first character is
      a quote character and if so, strip the leading character and
      remove the last quote character on the command line, preserving
      any text after the last quote character.
 

Always quoting the entire command line, regardless of these conditions appears to make Windows processes invoke successfully.

Parameters:
executable - executable that the shell has to call
arguments - arguments for the executable, not the shell
Returns:
List with one String object with executable and arguments quoted as needed
