This creates the interesting situation, that the JVM verifies stricter
if you not use the (Microsoft recommended) "cmd /C". (In fact the
implementation even documents this as a workaround if you want to
avoid the validation.)

Would it make sense to officially describe this in the exec(String[]),
that you can specify the path to a bat/cmd file as the first argument
and do not need to use the cmd /c?
