          VirtualMachine launch(Map<String,? extends Connector.Argument> arguments)
                         throws IOException,
                                IllegalConnectorArgumentsException,
                                VMStartException

      Launches an application and connects to its VM. Properties of the launch (possibly including options, main class, and arguments) are specified in `arguments`. The argument map associates argument name strings to instances of `Connector.Argument`. The default argument map for a connector can be obtained through `Connector.defaultArguments()`. Argument map values can be changed, but map entries should not be added or deleted.

      A target VM launched by a launching connector is not guaranteed to be stable until after the `VMStartEvent` has been received.

      Important note: If a target VM is launched through this funcctions, its output and error streams must be read as it executes. These streams are available through the `Process` object returned by `VirtualMachine.process()`. If the streams are not periodically read, the target VM will stop executing when the buffers for these streams are filled.

      Parameters:
        `arguments` - the argument map to be used in launching the VM.
      Returns:
        the `VirtualMachine` mirror of the target VM.
      Throws:
        `IOException` - when unable to launch. Specific exceptions are dependent on the Connector implementation in use.
        `IllegalConnectorArgumentsException` - when one of the connector arguments is invalid.
        `VMStartException` - when the VM was successfully launched, but terminated with an error before a connection could be established.
