Description
Currently it is possible for factories to preserve state from prior rounds, e.g. caching declarations.  This could give misleading results since the declarations from prior rounds are not valid in the current round's context.  One solution would be to throw an illegal state exception (or at least issue a warning) if a declaration was accessed after its round had ended.

Comments
While the ClassSymbols are re-used across the annotation processing rounds, Method and VariableSymbols are not. So the warning still may make sense for Method and VariableSymbol. This is probably a smaller problem, as the usecases to keep a non-Class Symbol seem rarer.

This issue should be reevaluated in light of the fix for JDK-8038455.

EVALUATION A different solution is to retain symbols across rounds. This may reasult as part of work to retain the same context across rounds.

EVALUATION One way of achieving this would be to install a special Completer in all Symbols after a round has completed. This completer would throw IllegalStateException. You can easily get at all symbols via Symtab.{classes,packages}.

EVALUATION Should be investigated. ###@###.### 2004-11-05 21:11:22 GMT
