JDK 8 RFR: 8009267: Restore isAnnotationPresent methods in public AnnotatedElement implementations

[Joe Darcy]

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
