And the JVM is the one implementing the language semantics (together 
with javac which feeds the JVM with bytecodes). Language semantcis are 
implemented by the combination of javac and JVM. If you say that this 
feature does not require any change to javac, you're just saying that 
you put all the burden on the JVM, but you *are* implementing the 
language semantics using annotations nevertheless...
