Hi Benedikt,
Thanks for the reply.
I will update the current code and make the following changes, then notify the mail list when
it is complete for further review.* Java 8 will be downgraded to Java 6. That's my own fault
for unit testing with lambda's.* I would prefer to keep the annotations (especially the tiny
net.jcip:jcip-annotations:1.0), but I will drop them and replace with javadoc.* I intended
this to go into commons-lang3, I will look at BeanUtils2 and make the appropriate changes.*
Since this idea looks like it will be included in Apache Commons (lang3) I will review Java
String and Guava String API's, to make sure nothing is missed (and add unit tests). That seems
unlikely though, StringUtils seems to cover all the bases.
Without having yet looked at BeanUtils2 (so this might be a moot question), would it be useful
to have a commons-lang3.fluent package or the like?
As for unit testing, do you want me to test all the delegating methods as well? It seems like
a lot of work for nominal gain.
Thanks again.

Hi folks,

Firstly, apologies if this results in a double post. I tried posting a couple of times, but
the first time I sent to the user list (sorry), and the second time I do not see my email
at all in the mail archive (
Hopefully 3rd time is the charm, and again, sorry for my n00biness.
I have written a fluent wrapper for the string utils class. Being new to commit anything to
Apache Commons, and given the nature of the change, I wrote up a first draft that I was hoping
the community could review, and then consider for addition to the commons library.
A copy can be obtained from If there
is a desire to add this to commons, I can complete any additional work required to meet the
Commons standard.

Thank you for your interest in Apache Commons Lang and my apologies for the late response.
The pre-christmas time is always pretty busy for me :-)Your Fluent String Utils wrapper looks
generally useful, however I'm not sure whether is fits into Commons Lang. Lang has a rather
conservative API design (meaning, we don't have any fluent APIs yet).
This would not be a blocker but the following definitely is:- Requires Java 8 - Lang is on
Java 6- Has dependencies to net.jcip:jcip-annotations:1.0 and org.jetbrains:annotations:15.0
- Lang should have little to no dependencies
So maybe you can simply publish this as an additional library for commons-lang3. If you would
like to work on fluent APIs, you should have a look at BeanUtils2 [1] which has a really nice
