    java.lang.NullPointerException

    2d7a3811-606b-4ecb-8d76-ca29aa043d53

      Hi,

      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.
