Re: [aspectj-users] problem with declare annotation

["Andy Clement" <andrew.clement@xxxxxxxxx>]

The error would appear to be a real bug, I put everything into one file:

aspect ConfigureTracing {
        declare @type : MyPojo : @Tracing(level = LoggingLevel.DEBUG);
// compile error!!!
        declare @method : * MyPojo.calculate() : @TestAnnotation;
}
@interface Tracing { LoggingLevel level(); }
@interface TestAnnotation {}
class Level {
  Level(int i) {}
  public final static Level ALL = new Level(1);
  public final static Level DEBUG = new Level(2);
  public final static Level ERROR = new Level(3);
  public final static Level FATAL = new Level(4);
  public final static Level INFO = new Level(5);
  public final static Level OFF = new Level(6);
  public final static Level WARN = new Level(7);
}
enum LoggingLevel {
        ALL(Level.ALL), DEBUG(Level.DEBUG), ERROR(Level.ERROR),
FATAL(Level.FATAL), INFO(
                        Level.INFO), OFF(Level.OFF), WARN(Level.WARN);
        private final Level level;
        private LoggingLevel(Level level) {
                this.level = level;
        }
        public Level getLevel() {
                return level;
        }
}
class MyPojo {
  public static void calculate() {
  }
}

and it still fails with the error you describe.  I have raised it on
bugzilla: https://bugs.eclipse.org/bugs/show_bug.cgi?id=211052

On the second situation, I don't think you can do what you want.  You
can raise an enhancement request and we can look at implementing
something.
