// Regression test for a map initialization order bug. The bug only manifests
// when:
//   1. A message contains map fields and is also extendable.
//   2. There is a file-level extension defined in the same file referencing
//      the above message as the extension type.
//   3. The program executes in the following order:
//        a. getDescriptor() is called on another message in the same file.
//        b. use protobuf reflection to access the map field.
// The symptom is a NullPointerException being thrown.
