JDK-6966604 - JavacFiler not correctly notified of lastRound
Description
Currently, the knowledge that warnings have occurred is lost across annotation processing rounds. This means that -Werror does not detect warnings that were generated in prior processing rounds.
Comments
EVALUATION See test test/tools/javac/processing/filer/TestLastRound.java to be added as part of fix for CR 6966604

EVALUATION -Werror is a hidden option that is just provided to simplify some types of regression testing. Any more sophisticated behavior (such as treating warnings as errors before, during or after annotation processing) can be better achieved through JSR199, and DiagnosticListeners, possibly in conjunction with a compiler TaskListener. Therefore there would not seem to be any requirement to make -Werror more sophisicated. However, it does seem reasonable to at least make -Werror work according to its current minimal spec (warnings cause a non-zero exit code) even in the face of annotation processing.
