Description

It seems that if an ontology registry (in RDF) contains a pair of triples such as

<Library1 meta:hasOntology Ontology1>
<Ontology1 meta:isOntologyOf Library1>

RegistryManagerImpl.populateRegistry() method enters an infinite loop.

This ends up in a StackOverflowError and the RegistryManagerImpl component failing to activate.

It should be possible to solve it by adding a check to a visitor method.
