[Java] Validate correctly the entire structure of specs for each Model type

[Batta32]

Describe the bug
A clear and concise description of what the bug is.
The current unit tests of Java doesn't validate correctly the spec structure for each model type. For example the DateParser.json specs, contains start property which is not validated in the DateTimeTest.java causing false positives.

To Reproduce
Steps to reproduce the behavior:

1. Go to DateTimeTest
2. See the structure that validates the assertResultsDateTime method
3. Compare the validated structure with the DateParser.json specs
4. See that not all the properties are validated

Expected behavior
A clear and concise description of what you expected to happen.
All the models should be correctly validated, checking the correct properties against to the specs.

Sample input/output
As applicable, add examples of text input and json output to help explain the problem.
