/*
 * Annotations.
 *
 * We're not expecting to make much use of runtime annotations, so speed vs.
 * space choices are weighted heavily toward small size.
 *
 * It would have been nice to treat "system" annotations in the same way
 * we do "real" annotations, but that doesn't work.  The chief difficulty
 * is that some of them have member types that are not legal in annotations,
 * such as Method and Annotation.  Another source of pain comes from the
 * AnnotationDefault annotation, which by virtue of being an annotation
 * could itself have default values, requiring some additional checks to
 * prevent recursion.
 *
 * It's simpler, and more efficient, to handle the system annotations
 * entirely inside the VM.  There are empty classes defined for the system
 * annotation types, but their only purpose is to allow the system
 * annotations to share name space with standard annotations.
