Description
Currently, most of javac's services and data get cleared between annotation processing rounds. That requires re-reading all classfiles, including those that originate on boot and compile classpath. If we could reuse the ClassSymbol from the boot and compile classpath as well as the javac services across annotation processing rounds, javac performance could be improved.

This is a fork of JDK-2206926.
