body: <p>I have following code:</p>
  
  <pre><code>options.addOption(OptionBuilder.withLongOpt(SOURCES)
                  .withDescription("path to sources")
                  .hasArg()
                  .withArgName("PATHS")
                  .create());
  ...
  CommandLineParser parser = new GnuParser();
  line = parser.parse(options, args);
  ...
  System.out.println(line.getOptionValues(SOURCES));
  </code></pre>
  
  <p>I invoke application with parameters</p>
  
  <pre><code>-sources=path1, path2
  </code></pre>
  
  <p>in result I see <code>["path1"]</code></p>
