Problem with FaCT++ 1.5.2 and OWLlink 1.2.0

Original [issue 35](https://code.google.com/p/factplusplus/issues/detail?id=35) created by dtsarkov on 2011-06-01T09:01:00.000Z:

What steps will reproduce the problem?

1. Running the latest version of OWLlink (1.2.0) with the libraries of FaCT++ 1.5.2 copied at the right place, as described in the readme file of OWLlink 2. Connecting to the OWLlink server via the Java OWL API (e.g. by calling the method OWLReasoner.getIndividuals)

What is the expected output? What do you see instead?

The OWLlink server should respond properly, but I get errors like this (on the client side of OWLlink):

OWLlinkErrorResponseException: Unable to register 'http://example.com/foo#myconcept' as a concept

No error or info is shown on the server side of OWLlink/FaCT++.

What version of the product are you using? On what operating system?

FaCT++ 1.5.2 OWLlink 1.2.0 on Ubuntu 11.04, 32bit

Please provide any additional information below.

It works with OWLlink 1.0.1 and FaCT++ 1.4.0. It also works with OWLlink 1.2.0 when other reasoners are used like HermiT. So, I assume that it must be a problem with FaCT++ version 1.5.x.
