DroolsStreamUtils fails with ClassNotFoundException when trying to deserialize KnowledgePackages with dependencies between them

I prepared a few unit tests demonstrating the erroneous behaviour, find them here:

https://github.com/maven-drools/drools-api-tests/tree/b41dc49666ab4a3946cf564817323116e86e8cb6

Run the tests from your favourite IDE after importing the project as a Maven project or from the command line.

Activate each of the three profiles in turn.

For Drools 5.1.1, both tests are green. For Drools 5.2.0.Final and 5.3.0.CR1, the test with dependencies will become red.
