OT: UDP server on solaris-i586/x64 misses 1st packet

[Weijun Wang]

Note: This is not about networking codes in JDK. Therefore OT.

I have a test (test/sun/security/krb5/auto/BadKdc*.java in @run/othervm 
mode) that starts a UDP server listening to requests from the same 
machine. The server is started in a daemon thread and 3 requests are 
sent at least 6 seconds later, with an interval of 2 seconds between 
each request. There is a probability of 20% that the server does not see 
the 1st request at all. The 2nd and 3rd requests are always received.

I use JPRT to run the test. This only happens on solaris-i586 and 
solaris-x64 platforms. The failure never happens on linux and windows.

Anyone knows what the reason might be? I've doubled the time intervals 
but seems there is no benefit.

BTW, the test actually sends 3x3 UDP requests to localhost, only the 
first 6 ones are sent to random ports.

Thanks
