code review request: 7122169: TcpTimeout fail for various reasons

[Weijun Wang]

Hi Alan

Do you have time to look at this fix?

http://cr.openjdk.java.net/~weijun/7122169/webrev.01/

I study the test again and find out it's not the same as those BadKdc* 
tests, where the port number must obey a pattern (n-th server on n****). 
So there is no need to assign one before the server socket is created. 
Also, it seems simply creating a server socket can simulate a timeout, 
no need to call accept() in a separate thread explicitly.

I've tried the new test with JPRT and it runs fine.

Thanks
Max

=== *Description* 
============================================================
sun/security/krb5/auto/TcpTimeout.java

The test fails intermittently on various systems for different reasons:

1. On all systems, it might fail if a port (random calculated) is 
already opened by another process.

2. In some Windows virtual machines, the wall clock might go slower than 
elapsed time. i.e. you can Thread.sleep() for 10 seconds but the change 
in System.nanoTime() results shows a smaller value.
