JMX MBeans under prefix “com.sun.corba” have been removed to work around a bug in the JMX support of the ORB, which consumes a large amount of heap memory for each application: https://github.com/eclipse-ee4j/orb/issues/5 . To this end, the Maven dependency org.glassfish.gmbal:gmbal has been replaced with org.glassfish.gmbal:gmbal-api-only.

If you have added dependencies to the org.glassfish.gmbal:gmbal in custom modules, then you must also replace those with org.glassfish.gmbal:gmbal-api-only. It’s not allowed to depend on both artifacts at once.

If you really require JMX MBeans for the Corba ORB and can accept increased heap memory usage, then you have to exclude the gmbal-api-only Maven dependency and replace it with the org.glassfish.gmbal:gmbal dependency again, for all applications in the Blueprint.
