Henri Yandell commented on CLI-162:
-----------------------------------
svn ci -m "Applying my second attempt at a patch to CLI-162. This fixes Gary's
reported bug (one of which was an example of CLI-162, and one a bug in my first
attempt to patch). Open question is whether to output text that is too long, or
try and break it up to fit the screen width. "

> Project: Commons CLI
> Issue Type: Bug
> Components: Help formatter
> Affects Versions: 1.1
> Reporter: Emmanuel Bourg
> Fix For: 1.2
>
> Attachments: CLI-162-take2.patch
>
>
> 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.
