> Root cause : Port for kdc service gets selected in the constructor, but we 
> bind to it later in MiniKdc.start()-->MiniKdc.initKDCServer() --> 
> KdcServer.start(). In meantime, some other service can capture the port which 
> results in BindException. The solution here is to catch the exception and 
> retry.
