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