> If you try to do a hasOption(null), you get a NPE:
> java.lang.NullPointerException
> 	at org.apache.commons.cli.Util.stripLeadingHyphens(Util.java:39)
> 	at org.apache.commons.cli.CommandLine.resolveOption(CommandLine.java:166)
> 	at org.apache.commons.cli.CommandLine.hasOption(CommandLine.java:68)
> Either hasOption should reject the null argument, or the function should simply return
false.  I think the latter makes more since, as this is how Java collections generally work.
