I am sure someone else can answer this for you but, if you are using something for free I don't think there will be an SLA. The license for downloading jboss open source tools/software is as it is , you can modify it if you want and etc. I am assuming "axios System" or the tool they are providing is not free?
Here is the jbpm license jBPM - Open Source Business Process Management - License
Hope this helps.
