can anyone help me with following problem? I get this error: "Error:  Entity: java.lang.NullPointerException" after applying design rules to my relational data model. Does anyone have an idea what does it mean?

I think the problem has something to do with java jre. But SQL Developer runs fine without any problems.

Thanks for your response.
