Hello!,

Please review the proposed fix for

Basically various parts of the compiler are ill prepared to handle the scenario where a non-annotation type is treated erroneously as an annotation. The present fix does two things: (a) "drops" the bogus annotation (after suitable errors have been reported) rather than persist in symbols. (b) since (a) is not enough to avoid trouble in all cases, proactive checks to avoid tripping the land mines are also put in place.

In the normal course of things, this crash would never be reported to users, since the compiler "swallows" crashes when an error has already been reported - except when annotation processing is on (or when -XDdev is used)

Thanks! Srikanth
