Be careful here - the java language requires two identical string
constants to be equal:
String s1 = "hello";
String s2 = "hello";
System.out.println(s1 == s2); // returns 'true'
The language spec also requires new instances of a String to *not* be
equal to the constant:
String s1 = "hello";
String s2 = new String("hello");
System.out.println(s1 == s2); // returns 'false'
Because of these distinctions, a compiler is not allowed to optimize in
the fashion you suggest.
