Change in org.omg.ORB.init breaks CORBA applications started with Webstart

    Details

    • CPU:
      x86_64
    • OS:
      windows_7

      Description

      FULL PRODUCT VERSION :
      java version "1.7.0_55"
      Java(TM) SE Runtime Environment (build 1.7.0_55-b13)
      Java HotSpot(TM) 64-Bit Server VM (build 24.55-b03, mixed mode)


      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows [Version 6.1.7601]

      A DESCRIPTION OF THE PROBLEM :
      CORBA Applications using alternative ORB implementations like JacORB or OpenORB configured by using following properties to configure the instances (JNLP snippet):

              <property name="org.omg.CORBA.ORBClass" value="org.openorb.CORBA.ORB"/>
              <property name="org.omg.CORBA.ORBSingletonClass" value="org.openorb.CORBA.ORBSingleton"/>

      no longer run when started with Webstart.

      It seems to be caused by a change in org.omg.orb.CORBA.ORB.init - usage of Systemclassloader instead of ContextClassLoader of the current thread as before


      REGRESSION. Last worked in version 7u51

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Configure an alternative ORB implementation using the mentioned properties.

      Write an (Webstart) application which instanciates the Singleton ORB by calling ORB.int()

      Start the application.


      ACTUAL -
      Exception occurs (Error org.omg.CORBA.INITIALIZE: can't instantiate default ORB implementation).

      REPRODUCIBILITY :
      This bug can be reproduced always.

      CUSTOMER SUBMITTED WORKAROUND :
      No Workaround.

      I've tried to put omg standard API JAR of the alternative implementation to <jre-home>/lib/endorsed/ but the implementation from rt.jar is still used.

      SUPPORT :
      YES
