Oracle periodically releases security updates (CPU see Oracle Critical Patch Update - July 2014 for latest) for all its software, Java is no exception to it.
At every CPU, the AutoVue team monitors the impact and documents the steps required to have AutoVue working properly with your integrations
For your reference, we attach the latest KM note here. It is a highly recommended reading for customers using AutoVue Client/Server Deployment.
