I believe the class com.sun.corba.se.internal.iiop.CDRInputStream.java class
has a bug in the read_Object(Class) method. It appears that this method
assumes that if the host component of the IOR is the current host, then the IOR
must contain a SUN ORB ServerId. The fragement of code that suggests this is
   if(s.equals(orb.getORBServerHost()))
   {
      int i = Utility.bytesToInt(abyte0, 8); // ArrayIndexOutOfBoundsException

The bytesToInt method will fail if the object key is less than 8 + 4 bytes. I
am running another ORB on the same host which generates small object keys.
When an IOR from this ORB came through JDK1.3 CDRInputStream.read_Object
(Class), I got the folloing exception:

 ERROR: java.lang.ArrayIndexOutOfBoundsException
 java.lang.ArrayIndexOutOfBoundsException at
 com.sun.corba.se.internal.util.Utility.bytesToInt(Utility.java:1041) at
 com.sun.corba.se.internal.iiop.CDRInputStream.read_Object
(CDRInputStream.java:605) at
 com.sun.corba.se.internal.iiop.CDRInputStream.read_Object
(CDRInputStream.java:577)

It is not safe to assume the size of the IOR's Object key

I potential solution would be to check both host and port before performing the
bytesToInt method
   if(s.equals(orb.getORBServerHost()) && port == orb.getORBServerPort())
