I have a web page with an applet and I can add other applets to this page in runtime. These applets need to communicate with the first applet, so they all must be run in the same JVM instance. But since the last Java Plug-in update (10.4.1.255) it became impossible. New applets occasionally start in new JVM. separate_jvm=false doesn't solve the problem.
You can test it with this demo: http://demo.aurigma.com/ImageUploader7/MultipleDescriptionsDemo/Default.aspx. Just add some images; thumbnail applets started in new JVM cannot connect to uploader applet.
Is there any way to launch all applets in the same JVM instance?
