during a Maven build BTW.
> infinite loop in the wrapping code of HelpFormatter
> ---------------------------------------------------
>
> Key: CLI-162
> URL: https://issues.apache.org/jira/browse/CLI-162
> Project: Commons CLI
> Issue Type: Bug
> Components: Help formatter
> Affects Versions: 1.1
> Reporter: Emmanuel Bourg
> Fix For: 1.2
>
>
> If there is not enough space to display a word on a single line,
> HelpFormatter goes into a infinite loops until the JVM crashes with an
> OutOfMemoryError.
> Test case:
> {code}
> Options options = new Options();
> options.addOption("h", "help", false, "This is a looooong description");
> HelpFormatter formatter = new HelpFormatter();
> formatter.setWidth(20);
> formatter.printHelp("app", options); // hang & crash
> {code}
> An helpful exception indicating the insufficient width would be more
> appropriate than an OutOfMemoryError.
