Java 7 is my system default JRE on all new web browsers to JR 7 Configured to open, such as the default Netbeans has prepared Java 8 on a new instance, because its 'isolated' defaults (separate in the context of the rest of the system). Consider the scenario: Chrome is up and running fine, I'm inspired by code and then open Netbeans. When Netbeans loads, Chrome's Java is funky - I now have JavaScript Can not interact with applet (like Chatanda handshake does not happen, scrollbar becomes non-responsive, has a host of any other discrepancies). I take the steps to resume Chrome, and the frame does not either load out of the "defined" layout on the page, or do not stack. Keep in mind, I'm (deliberately) running any Java 8 program outside Netbeans. Why does this happen? My suspicion is that JRE8 system replaces pointers for API calls in AP .. I would agree that JR sandbox would expand in that machine version library, but it does not seem like that....
