Solution

  • In JDK 9, the module java.corba which contains the interface org.omg.CORBA.portable.IDLEntity is not resolved by default and has to be manually added:

    Add the module java.corba to the Explicitly included modules as described in this answer for java.xml.bind or use a Java 8 JRE/JDK.

    See blog post Prepare for JDK 9 by Yolande Poirier (emphasis by me):

    Six Java EE libraries in JDK are no longer shared by default in JDK 9. Those Java EE deprecated APIs are java.corba, java.transaction, java.activation, java.xml.bind, java.xml.ws, java.xml.ws.annotation. They have been deprecated in JDK 9 and will be removed in a future release. They are disabled by default in JDK 9. Their packages will not compile in Java 9 and give an error message. The documentation gives you migration options to enable those libraries in JDK 9. This should be a temporary solution because they are scheduled to be removed in a future release.
