The Eclipse workbench is running on a Java 6 JVM, with com.sun.mirror.apt.AnnotationProcessorFactory in the classpath.

Resolving the problem

Launch Eclipse with a Java 7 JVM that does not contain com.sun.mirror.apt.AnnotationProcessorFactory in the classpath.

To specify which JVM to use when starting Eclipse, use the -vm runtime option.
