Runtime.exec, unlike system()-like functions in other languages, does not invoke a shell to parse the command (and double quoted strings are a shell feature).

To split the string the way you want it, use the Runtime.exec that accepts a String array:

Runtime.getRuntime().exec(new String[] { "java", "MyClass1", "-exec", "java MyClass2 arg1 arg2"});
