What is your Github address for the project?

I have no problem, when I make an "mvn clean package" to the original Protégé code. I managed to execute and debug without any problem, because of that I was able to learn how Protégé works. The problem occurs when I add my class and enumerative package. It compiles well, but when I try to execute or debug, the error already commented appears. If you consider it, I can send you my project with the changes made to the source code of Protégé, there are not many so far. I just modified the "refill" method of the "OWLDataPropertyAssertionAxiomFrameSection" class that is in
"Org.protege.editor.owl.ui.frame.individual", in order to extract the "Property assertions" from my ontology that are in a Databases and not in the OWL file.

 Attached file "protect.log".
 I am incorporating functionalities into the Protégé project. But I'm having problems when I try to debug from the IDE Eclipse.
 I added a package called "org.protege.editor.owl.bigontology", inside I added my classes and enumerative types. Everything compiles well when I do an "mvn clean package", I attach an image of the result in the console. However, when I try to debug from Eclipse, I get an error message: "An error occurred that prevent Protégé from Starting", also attached the image. "
 I have been reviewing the code and detected that the exception is thrown in the line "framework.start ();", belonging to the method "start", class "Launcher".

Within the "start" method, the error occurs when the following line of code is executed:
"// Send a framework event to indicate the framework has started.
         FireFrameworkEvent (FrameworkEvent.STARTED, this, null); "

Within the "fireFrameworkEvent" method, only the following line of code is executed:
"M_dispatcher.fireFrameworkEvent (new FrameworkEvent (type, bundle, throwable));"

"Type" = 1, "bundle" is an information object and "throwable" = null;

Any help that allows me to identify the reason for the error?

Best regards.
