Error dialog screenshot

Description of problem:
Data model doesn't load. Error message is displayed (explaining nothing at all). NullPointerException printed in server log.

Version-Release number of selected component (if applicable):
ER5

How reproducible:
-

Steps to Reproduce:
1. Create a class with public field, no getter, no setter
2. Commit and push into existing project in Business Central
3. Server restart may be needed to pick up the model change
5. Navigate to the project, open Data Modeler

Actual results:
Error dialog in UI, NPE in server log. No hint on which file (class) in the model is causing the problem. NPE stack trace in stderr doesn't contain any helpful information, following GenericPortableException doesn't include a relevant cause.

Expected results:
No error. Or, if the POJO encountered is not valid, then error message explaining which file is that and what is the problem.
