JacORB Change History

The changes made to JacORB are listed below according to JacORB release version number. Please note that bug fixes are listed on the JacORB Fixed Bugs page.

3.0.0.0

• ORB
  • Removed finalize from Delegate to improve performance and scalability. Client code is now responsible for calling _release on CORBA Objects as necessary (JAC#741).
  • Fix so the optimised key cache will auto-switch off for both client and server if it detects an older jacorb version (JAC#690).
  • Added jacorb.key.cacheSize property to allow the optimised key cache to be configured and improved purging algorithms (JAC#656).
  • Enhanced disableServiceContextNegotiation property to disable on both client and server side (and fixed its spelling) (JAC#656).
  • Removed sync from GIOPConnection.getTransport to fix deadlock with callback issue (JAC#649).
  • Enhancement to implement the correct use of portable interceptors when dealing with local calls, including the handling of ForwardRequests (JAC#647).
  • Added dummy implementation of Delegate::_get_component, which returns null (JAC#645).
  • Enhancement to add the jacorb.enableNullString option to marshall null strings (JAC#639).
  • An implementation of the Object::create_request operation has been added with an exception list (JAC#631).
  • Fix for NullPointer access in org.jacorb.orb.Delegate (JAC#772).
  • Allow OAIAddr to be specified when using PortRangeSocketFactory (JAC#629).
  • Split jacorb.disableServiceContextNegotiatation into a separate property from jacorb.interop.comet (JAC#577).
  • Added Object._get_component () to OMG stub code from OMG 03-01-02 (JAC#489).
  • JacORB now implements the Endorsed Standards Override Mechanism as described in http://java.sun.com/j2se/1.5.0/docs/guide/standards/index.html (RTJ#736).
• POA
  • Modified AOMRemovalThread to shutdown on POA destruction (JAC#696).
• IDL Compiler
  • An enhancement has been made to the idl compiler to implement the correct use of portable interceptors when dealing with local calls (JAC#647). idl generated code must be recompiled as the idl compiler changes will now cause failures for cases involving local objects and portable interceptors. This is because:
    • The SEND_REPLY or SEND_EXCEPTION points on the server side will not get called if a call is invoked on a local server. This will result in a BAD_INV_ORDER exception when trying to access attributes that are not available because the call status has not been set to send_reply or send_exception.
    • If a ForwardRequest is thrown from servant_previnoke (and so the ServantObject is null) a CORBA.UNKNOWN exception will be thrown with the message "local invocations not supported";.
    • Some interception points will not get called, as described above and also at the RECEIVE stages on the client side if an invocation is made to a local servant.
  • Enhancement to the IDL compiler to generate a toString () implementation for Union types (JAC#643).
  • Enhancement to ant JacIDL task to pass sloppyidentifiers and i2jpackagefile through, add error checking and add comments to generated code to silence Eclipse warnings (JAC#608).
• Bug fixes
  • ORB
    • Fix for profile selection in bind/rebind for group IOR (IOGR) (JAC-62).
    • Fix to propagate objectId to ServerRequestInfo for local calls.
    • Fix for non-configured CDRInputStream when created with an ORBSingleton (JAC#703).
    • Fix to ensure that current contexts are added and cleared correctly when handling embedded calls (JAC#685).
    • Change to ensure that the REQUEST_DURATION_POLICY timeout is not overwritten if an interceptor makes an embedded invocation (JAC#677).
    • Fix so that the idl compiler detects bounds violations for the string type (JAC#676).
    • Change to request handling to ensure that Relative Roundtrip Timeout will bound the entire user invocation including any transparent re-invocations following LOCATION_FORWARD or other retryable exception conditions and also embedded invocations (JAC#670).
    • Fixed delegate bind issue to prevent cached object delegate being set to null (JAC#663).
    • Fixed a memory leak in Delegate pending_replies if an error happens when reading the reply (JAC#662).
    • Fix for Current overwriting in local calls between Client/ServerRequestInfo (JAC#660).
    • Fix to reduce the number of threads created when deactivating an object; backport-util-concurrent.jar has been added and should be used when the JDK is pre 1.5 (JAC#652).
    • Fix for attribute setting of the jacorb.security.ssl.client.protocols and jacorb.security.ssl.server.protocols properties (JAC#651).
    • Fix for POA::reference_to_id error checking (JAC#646).
    • Fixed a memory leak in ObjectKeyMap (JAC#642).
    • Fix for NullPointerException within Delegate when multiple threads call release (JAC#630).
    • Workaround fix for InterruptedIOException in IIOPListener from LogKit and native code (JAC#622).

• Bug fixes

    • string_to_object throws BAD_PARAM instead of INV_OBJREF if the conversion of a stringified ior fails.

• ORB
  • add IORMutator plugin.
  • add property to disable client orb policies to improve performance.
  • change default connect_timeout to 90000 (JAC#217).
  • new property: jacorb.codeset. By default this is on. If off, JacORB will ignore all codeset component info profiles and will turn off explicit marshalling with codesets (re Strings). Fixes for char transmission.
  • New properties are available for assigning protocol-independent addresses:
    • OAAddress=<protocol_name>://<protocol_address> for example: OAAddress=iiop://myhost:1234

      OAIAddr and OAPort are still used to make IIOP-specific addresses but are superceded by OAAddress.

    • jacorb.ior_proxy_address=<prot_name>://<prot_addr> supercedes jacorb.ior_proxy_host and jacorb.proxy_port

The default for this property is off, unlike previous releases, where this check was always done.

  • Added WrongTransaction to idl.
  • Added DIOP IOR decoding ability.
  • Performance Improvements.
  • You can now use IORInterceptors to add new profiles to IORs (rather than just adding components to profiles that were created by the ORB). To achieve this, the IORInfo object that is passed to IORInterceptors now implements a special JacORB interface, org.jacorb.orb.portableInterceptors.IORInfoExt. This interface provides methods to look up existing profiles and add new ones to an IOR.
  • Rename property jacorb.connection.server_timeout to jacorb.connection.server.timeout, for consistency.
