really?  must be some downstream distro patch, that's not what upstream
does, we build it with ant in
external/apache-commons/ExternalProject_apache_commons_lang.mk  etc.

(see in particular commit 89db5b5b88508e55bce50240d248dd26053f4e09,
"Apache Commons Lang 3.3.1 at least requires Java 1.6 and non debug
version")
