 /*
  * This test operates in phases to test retrieving the qualified name
  * of anonymous classes from type elements modeling the anonymous
  * class.  The type elements are generated using both source files and
  * class files as the basis of constructing the elements.
  *
  * Source files will be tested by the @compile line which runs
  * TestAnonSourceNames as an annotation processor over this file.
  *
  * Class files are tested by the @run command on this type.  This
  * class gets the names of classes with different nesting kinds,
  * including anonymous classes, and then invokes the compiler with an
  * annotation processor having the class files names as inputs.  The
  * compiler is invoked via the javax.tools mechanism.
