Claude Warren updated CLI-351:
------------------------------
Description:
Analysis shows this is not a regression of CLI-162 but a different problem with
similar user experience.
As reported by Damien Carbonne:
Starting with commons-cli-1.10.0, HelpFormatter enters an infinite loop when
its is passed a header or footer that contains 2 or more new line (\n)
characters. The following code shows this behaviour:
{{final HelpFormatter formatter = HelpFormatter.builder().get();}}
{{formatter.printHelp("CL syntax",}}
{{ "Header\n\n",}}
{{ Collections.emptyList(),}}
{{ "Footer",}}
{{ true);}}
