Hi Sankar,

I suppose you mean WebObjects 5.4.3 and Java 8, as there is not yet any JDK 9 specified, much less released, and WO 4.x wasn’t even Java-based.

Nevertheless, those sun.* API uses have to be cleaned up sooner or later, yes. I’m sure this will happen soon as JDK 8 gets adopted. But this can mean some amount of work to substitute things with other libraries, which might break compatibility for some existing code. Feel free to submit a pull request yourself :-)

Hi All,

  https://blogs.oracle.com/java-platform-group/entry/closing_the_closed_apis

  I am using WebObject 4.3 and when I execute Jdeps i am seeing few WebObjects modules uses Java closed APIs. Is there any plan to release new version to support JDK 9?

 

Snapshot of the result :

ERExtensions.jar -> javawebobjects.jar
   er.extensions.components.ERXGracefulShutdown (ERExtensions.jar)
      -> sun.misc.Signal                                    JDK internal API (rt.jar)
      -> sun.misc.SignalHandler                             JDK internal API (rt.jar)
   er.extensions.eof.ERXEC (ERExtensions.jar)
      -> sun.misc.SignalHandler                             JDK internal API (rt.jar)
   er.extensions.eof.ERXEC$DumpLocksSignalHandler (ERExtensions.jar)
      -> sun.misc.Signal                                    JDK internal API (rt.jar)
      -> sun.misc.SignalHandler                             JDK internal API (rt.jar)
   er.extensions.eof.ERXObjectStoreCoordinator$DumpLocksSignalHandler (ERExtensions.jar)
      -> sun.misc.Signal                                    JDK internal API (rt.jar)
      -> sun.misc.SignalHandler                             JDK internal API (rt.jar)
   er.extensions.foundation.ERXSignalHandler (ERExtensions.jar)
      -> sun.misc.Signal                                    JDK internal API (rt.jar)
      -> sun.misc.SignalHandler                             JDK internal API (rt.jar)
   er.extensions.jdbc.ERXJDBCUtilities (ERExtensions.jar)
      -> com.sun.rowset.CachedRowSetImpl                    JDK internal API (rt.jar)
   er.extensions.jdbc.ERXJDBCUtilities$3 (ERExtensions.jar)
      -> com.sun.rowset.CachedRowSetImpl                    JDK internal API (rt.jar)

 

Thanks
