> NullPointerException in Util.stripLeadingHyphens when passed a null argument
> ----------------------------------------------------------------------------
>
> Key: CLI-133
> URL: https://issues.apache.org/jira/browse/CLI-133
> Project: Commons CLI
> Issue Type: Bug
> Components: CLI-1.x
> Affects Versions: 1.0, 1.1
> Reporter: Brian Egge
> Priority: Minor
> Fix For: 1.1

> Attachments: bug133.patch

>
> 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.
