Source build: ClassCastException AquaMenuBarUI on Mac OSX

Hi,

 

I built RapidMiner 7 from source and managed to get it running in IntelliJ IDEA. Even so, I don't see the main menu at the top. I do see this menu when I install and run RapidMiner from the DMG package directly. I get the log and stack trace below after starting the source-built version. Something seems to be going wrong when instantiating the menu. I'm running Java 8 (build 1.8.0_102-b14) and OSX El Capitan.

 

Anyone seen this before?

 

Cheers,

    Hi,

     

    you are looking for the following system properties:

     

    // set system properties to allow menu bar shown in OS X menu bar (old + new version)
    System.setProperty("com.apple.macos.useScreenMenuBar", "true");
    System.setProperty("apple.laf.useScreenMenuBar", "true");

     

    Regards,

    Marco
