Looks good to me!
Are this the only methods in the corelib that were removed in favour of a
default implementation in the interface?
I would not described the method as "removed," but to my knowledge
AnnotatedElement.isAnnotationPresent was the only existing interface
method in the core libraries replaced by a default method. The intended
use case for default methods is adding new methods to interface and that
change has certainly been done in other parts of the API.

Subject: JDK 8 RFR: 8009267: Restore isAnnotationPresent methods in public
AnnotatedElement implementations
Hello,
The changes pushed under
8007113: Upgrade AnnotatedElement.isAnnotionPresent to be a default
method
http://hg.openjdk.java.net/jdk8/tl/jdk/rev/e04467fa13af
combined with how javac currently models default methods under pre-JDK-8
source versions can result in some source compatibility impacts for those
using JDK 8 to compile under older source versions if the recommended
practice of setting the bootclasspath is not followed. [1]
To mitigate these impacts, I'm proposing the changes in
8009267: Restore isAnnotationPresent methods in public
AnnotatedElement implementations
http://cr.openjdk.java.net/~darcy/8009267.1/
which have the effect of restoring a concrete isAnnotationPresent method
to Class, Package, Field, Method, and Constructor. The implementation
delegates to the default method on the AnnotatedElement interface.
Thanks,
-Joe
