How to configure Neoload with ORACLEFORMS?

Hello,
I am trying Neoload free version, in order to see if we could use it to automize our tests and to stress our Oracle Forms application. Currently I'm not able to use it and I don't know if it's possible so. I'm in front a issue... but nothing to do. I join a screenshot od the error. A part of the exception details is :
ERROR - neoload.Engine: Cannot send Oracle Forms dialog message : Key negociation has failed com.neotys.nl.conversion.plugin.g.a.f: Critical error: encryption key negociation with server failed
