Passing nested class names on javac command line interfere with subsequent name -> class lookup

As part of JSR 269, javac started to accept the names of class files to undergo annotation processing. However, if the set of names includes multiple names of nested classes, subsequent lookups fail, even if independent compiles with the same class path find each class file.

These failures occur for the names of the classes generated from the NestingExamples code listed at
http://java.sun.com/javase/6/docs/api/javax/lang/model/element/NestingKind.html
