I think I should add javaDoc at the same time, add a new example.

<tr><td>"java.lang.String"</td><td>16</td><td>"java.lang.String"</td></tr>

Can you update the Javadocs to include an example of a call with a class name, and len with the exact class name length, and its expected output, please?

+1, added a review comment for @verhas . And @verhas , thanks a lot for your contributions, we should be able to merge them soon (unless we need to wait for a major release, then I will update JIRA issues accordingly)

@verhas I think this and #446 are good to be included in the next release. Just need you to address the review feedback and update both branches. If you could rebase it onto master as well, please. I've just fixed the Checkstyle issues, and Travis build should pass for both 👍

Thanks

This request became outdated as the method to be fixed was refactored 100%.
