UDP client/server communication failed with jdk1.3.1 on Win 98 machine when DatagramPacket buffer size is more than 8k. It doesnt throw any exception also. Client/Server communication came to halt . Same tests passed on Win NT and Sol x86. Even on Win 98 client/server communication passed with DatagramPacket buffer size 1k, 4k and 8k.

How to reproduce this bug:

1. Get the networking test suite from :
   /net/sqesvr/export/vsn/NET/merlin_jdk_net_promoted/tests

2. Take Win 98 machine.

3. Open two command windows for server and client. In both server and client windows set the JAVA_HOME to jdk1.3.1 build 12
STABLE_JAVA_HOME to jdk1.3.

4. Do a 'make all ' in tests folder. Move to udp sub directory under tests.

5. In server window execute the following script
     $ run_udp_server

6. In client window execute the following script as shown
    $ run_udp_client -quick -1 serverName

7. The tests with buffer size up to 8k will be passed . In run_udp_client.ksh script udpClient has been called with different buffer sizes. You can give different buffer sizes over there.

Other Information:

Same tests passed on Win NT and SolX86 machines.
