My understanding of the printMessage (and I might be wrong) is that we  
added a printMessage to a Massager which is packaged within rt.jar.   
When using the binary release, javac finds Massager in rt.jar before  
the modified tools.jar, and then we get method not found error.

If we modify ElementType then we would need to need to either mutate  
rt.jar or complicate the installation procedures.
