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
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.
