Description

When using reflection based auto serialization and the CLI Geode Native client, it is required that any domain objects implement default constructors.  If a default constructor isn't implemented, then serialization fails ungracefully with a null reference exception.  Better error handling for this case should be added.

Steps to reproduce:

1. Open the PdxAutoSerializer example in the examples packaged with geode-native
2. Remove the default constructor from the Order class
3. Run the example and observe the null reference exception

Acceptance criteria:

A test should be written which captures the same steps to reproduce described above. Better error handling which indicates the root of the issue should be implemented, rather than throwing a null reference exception.
