java version "1.3.1-rc1"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1-rc1-b21)
Java HotSpot(TM) Client VM (build 1.3.1-rc1-b21, interpreted mode)

A CORBA client hangs with JDK1.3.1-RC1, though it works well with JDK1.3.0 and
JDK1.2.x.
Invoking remote method does not reach at CORBA server.

CORBA Server:
    INTERSTAGE V3.0 (Fujitsu)


1. IDL as follows:
    module ACCOUNTS {
        interface MOMAINIF {
            long MAINPROC( inout string inoutustring );
        };
    };

2.Compiling IDL and insert debugging information:
    c:\> c:\jdk1.3.1\bin\idlj ACCOUNTS.idl
    
    Then, edit _MOMAINIFStub.java. (_MOMAINIFStub.#MAINPROC())
          public int MAINPROC (org.omg.CORBA.StringHolder inoutustring)
          {
            org.omg.CORBA.portable.InputStream _in = null;
            try {
               org.omg.CORBA.portable.OutputStream _out = _request ("MAINPROC",true);
               _out.write_string (inoutustring.value);
          System.out.println("start _invoke()"); // for debugging
               _in = _invoke (_out);
          System.out.println("finish _invoke()"); // for debugging
               int __result = _in.read_long ();
               inoutustring.value = _in.read_string ();
               return __result;
            } catch (org.omg.CORBA.portable.ApplicationException _ex) {
               _in = _ex.getInputStream ();
               String _id = _ex.getId ();
               throw new org.omg.CORBA.MARSHAL (_id);
            } catch (org.omg.CORBA.portable.RemarshalException _rm) {
               return MAINPROC (inoutustring);
            } finally {
                _releaseReply (_in);
            }
          } // MAINPROC
    
    c:\> c:\jdk1.3.1\bin\javac ACCOUNTS\*.java

3.CORBA client source as follows:
    class iorTest {
        static ORB orb = ORB.init( "ACCOUNTS.ior", null );

        public static void main(String[] args) {
            ACCOUNTS.MOMAINIF accounts;

            org.omg.CORBA.Object obj = getObject(args[0]);
            accounts = ACCOUNTS.MOMAINIFHelper.narrow(obj);

            StringHolder wk_msg = new StringHolder("test string");
            int ret = accounts.MAINPROC(wk_msg);
            System.out.println("ret = " + ret);
            System.out.println("wk_msg = " + wk_msg.value);
        }


        public static org.omg.CORBA.Object getObject( String filename ) {
            try {
                BufferedReader fin = new BufferedReader(new FileReader (filename ));
                String line = fin.readLine();
                fin.close();
                return orb.string_to_object(line);
            } catch ( Exception e ) {
                e.printStackTrace();
            }
            return null;
        }
    }


4.ACCOUNTS.ior as follows:
    
IOR:010000001a00000049444c3a4143434f554e54532f4d4f4d41494e49463a312e300000000100
0000000000006b00000001010000070000006170746976610000421f000053000000000200003ac1
6c9e000001bc0000001a49444c3a4143434f554e54532f4d4f4d41494e49463a312e300000000000
001a49444c3a4143434f554e54532f4d4f4d41494e49463a312e3000000000000000000000


5.Running CORBA client:
    C:\> c:\jdk1.3.1\bin\java -cp . iorTest e:\etc\ior\ACCOUNTS.ior
    start _invoke()

        ... It hangs. The message "finish _invoke()" is never printed.
    
    C:\> c:\jdk1.3\bin\java -cp . iorTest e:\etc\ior\ACCOUNTS.ior
    start _invoke()
    finish _invoke()
    ret = 0
    wk_msg = xxxxxxxxxxxxxxxx

        ... There is no problem.
