/*
* There are several cases this test fails:
*
* 1. The random selected port is used by another process. No good way to
* prevent this happening, coz krb5.conf must be written before KDC starts.
* There are two different outcomes:
*
* a. Cannot start the KDC. A BindException thrown.
* b. When trying to access a non-existing KDC, a response is received!
* Most likely a Asn1Exception thrown
*
* 2. Even if a KDC is started, and more than 20 seconds pass by, a timeout
* can still happens for the first UDP request. In fact, the KDC did not
* received it at all. This happens on almost all platforms, especially
* solaris-i586 and solaris-x64.
*
* To avoid them:
*
* 1. Catch those exceptions and ignore
*
* 2. a. Make the timeout longer? useless
* b. Read the output carefully, if there is a timeout, it's OK.
* Just make sure the retries times and KDCs are correct.
* This is tough.
* c. Feed the KDC a UDP packet first. The current "solution".
