More specifically, the new Generated annotation type is tied to the 
java.compiler module rather than the java.xml.ws.annotation module which 
houses the old Generated.

After additional discussion, it seemed preferable to put the generated 
annotation in a module related to code generation of some sort, 
java.compiler, rather than the universally imported module java.base.
