It depends on the underlying OS. (The following is true for Win2K)

The "start"-command is not a standalone command. It is included in the
cmd.exe To execute something using the start-command one needs to execute
"cmd /c start <mycommand>". In Ant this reads

<exec dir="." executable="cmd.exe">
  <arg value="/c"/>
  <arg value="start"/>
  <arg value="java"/>
  <arg value="${serverclass}"/>
</exec>
