Description of problem:

Validation of classes in dependencies was added for https://bugzilla.redhat.com/show_bug.cgi?id=1007055.

This however leads to a failure to compile a project or load a DataModelOracle (used to drive rule authoring) when a single class lacks all required dependent classes (which was the subject of BZ1007055). 

In order to use @PropertyReactive kie-api needs to be added as a project dependency, this however refers to "optional" (maven scope "provided") dependencies that are not included in either the JAR uploaded or the workbench. Consequentially, due to BZ1007055, it is impossible to use @PropertyReactive.

@PropertyReactive is in kie-api.

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

6.0.x

How reproducible:

Always

Steps to Reproduce:
1. Add kie-api as a project dependency, to use @PropertyReactive.
2. Problems panel gives a list of errors; and rule authoring is impossible.

Actual results:

It is impossible to use @PropertyReactive.

Expected results:

Advanced users should be able to add kie-api as a project dependency to use @PropertyReactive.
