            Bug ID: 999
           Summary: Unexpected string terminator on marshaling huge

client-server example that reproduces the bug on marshaling huge strings

I've experiencing a MARSHAL exception when I use a huge string as parameter (or
even as return value). In my test, I used a 10000 length string containing the
char '1'.

Exception on server-side:
org.omg.CORBA.MARSHAL: unexpected string terminator value 31 at buffer index
108
    at org.jacorb.orb.CDRInputStream.read_string(CDRInputStream.java:1253)
    at test.bigsize.TestPOA._invoke(TestPOA.java:46)
    at
org.jacorb.poa.RequestProcessor.invokeOperation(RequestProcessor.java:350)
    at org.jacorb.poa.RequestProcessor.process(RequestProcessor.java:672)
    at org.jacorb.poa.RequestProcessor.run(RequestProcessor.java:830)

IDL:
module test
{
    module bigsize {
        interface Test {
            void input(in string s1);
        };
    };
};

Part of message request (I used jacorb.debug.dump_outgoing_messages=on):

I can see the error on "00 00 00 01", it should be the size of string and not
0x1.

When I tried JacORB 3.4 (and lower versions) it works fine and I got "00 00 27
11" as expected instead of "00 00 00 01".

In order to execute my test (attached):
mvn compile
mvn dependency:copy-dependencies
./runserver
./runclient

Thank you in advance,
