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
