Description

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.

Can this utility be made to not fail if address taken? Try another?
