Code:
@MyAnnotation( value=5, foo=6 )
public class Class2 {
}
@interface MyAnnotation {
    int value();
}

The error is marked at the value '6', not the identifier 'foo':
Class2.java:1: error: cannot find symbol
@MyAnnotation( value=5, foo=6 )
                                             ^
  symbol: method foo()
  location: @interface MyAnnotation
1 error

This worked fine in JDK7 but is broken in JDK8
