E-invoicing to OpenPeppol with Oxalis on CentOS anyone ?

Hello list,

I'm desperately trying to get the latest Oxalis software
(<a href="" title=""></a> )
to run in Tomcat on CentOS 6.9 but I'm getting a obscure Java error. Something
about a a method not found:


Has anyone succesfully implemented this on CentOS 6.x ?

Tomcat is running fine behind Apache. All software up to date.
Tried many things already, also install Oxalis from source but that fails with
different problems.
I found that OSCP checking is default disabled in Java (true ?) and tried to
enable it with by adding the commandline switches:
java \

but no luck

I filed a bug report on github, details about the exact error:

Any help appreciated.
