Exception in thread "main" org.jruby.exceptions.RaiseException: (LoadError) no such file to load -- thread_safe/jruby_cache_backend
The file exists, so I am guessing that there is a problem mixing classpaths and versions that come from the OS installation:
Asciidoctor PDF 1.5.0.alpha.15 using Asciidoctor 1.5.5 [http://asciidoctor.org]
Runtime Environment (ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]) (lc:UTF-8 fs:UTF-8 in:- ex:UTF-8)
and those packages that come with the maven installation of asciidoctorj (1.5.4).
So finally my questions:
* is my java Syntax for adding extensions from filesystem and gems right?
* is there a clean way I can proceed to do what I am trying to?
