jdk 1.7.25 doesn't work for my project over windows server 2003

Question

I have a jdk version updated from jdk 1.7.21 to jdk 1.7.25, build on Solaris 10 and production runs over windows server 2003. I have not updated any java code this time, since build was a success, I would update java code if compile hits an error, e.g on jdk from 1.6.45 to jdk 1.7.xx, I have to update a few files to match jdk 1.7 API changes, then it's running fine, there was a few updates from jdk 1.7.xx to jdk1.7.21, each time updated was fine. But this time, after build jdk 1.7.25 from 1.7.21 source code, compile was ok, but run time the server runs up ok, but client is stuck in the middle - there is a SESSION_ADAPTER build failed, we used OPNORG 1.2 which is over 10 years old, and a 3rd party binary code only. Wondering where is the really problem on jdk 1.7.25?

I used "old school" skills to print out which line was broken, it looks stuck in the function of narrow(orb), got an Exception of "BAD_PARAM":

Here is the java file(It's generated by CORBA IDL, we do not have source of OPNORG):

package DPEM.src.presentation.adaptation.adaptationIfc;

    if ( obj._is_a( id() ) )
    {
        _SessionAdapterStub stub = new _SessionAdapterStub();
        stub._set_delegate( ((org.omg.CORBA.portable.ObjectImpl)obj)._get_delegate() );
        return stub;
    }

    throw new org.omg.CORBA.BAD_PARAM();
}

    _SessionAdapterStub stub = new _SessionAdapterStub();
    stub._set_delegate( ((org.omg.CORBA.portable.ObjectImpl)obj)._get_delegate() );
    return stub;

}

}

I have no idea for the past a 2 weeks, hopefully can borrow a little of java/IDL skills from you gurus.

Thanks, Curtis
