The JDK ORB has a bug when dealing with repository id lists in valuetypes. When reading these we sometimes see  this exception:

Exception in thread "main" java.rmi.RemoteException: CORBA INTERNAL

N/A

There is a problem in CDRInputStream_1_0.java:

              // read first array element and store it as an indirection to the whole array
            int indirection = get_offset() - 4;
            String repID = read_repositoryId();
            if (repositoryIdCache == null)
                repositoryIdCache = new CacheTable(false);
            repositoryIdCache.put(repID, indirection);

indirection is bbwi.index - 4, but after read_repositId(), if the read result is not null  --- stringIndirection will not be equal to indirection above: in readStringOrIndirection:

        int len = read_long();   <---- bbwi.index += 4

        //
        // Check for indirection
        //
        if (allowIndirection) {
            if (len == 0xffffffff)
                return null;
            else
                stringIndirection = get_offset() - 4; <---- is the original position, not original position - 4! 
        }

So, this will cause the put function is CacheTable triger that exception ---- same key for different vals. The fix might be like:
int indirection = get_offset();
