// We test all the "illegal" relationships between a nest member and its nest-host
// except for the case where the name of the nest-member matches the name listed
// in the nest-host, but resolves to a different class. There doesn't seem to
// be a way to construct that scenario.
// For each nested class below there is a corresponding .jcod file which breaks one
// of the rules regarding nest membership. For the package related tests we have
// additional PackageNestHost*.java sources. We also have NotAMember2.java.
// Note that all the .java files must be compiled in the same step, while all
// .jcod files must be compiled in a later step.
