Re: 2 JavaFX applets in the same JVM
In general the number of JREs used to run applets and sharing of JREs should be expected to be indeterminate. The deploy code attempts to minimize the number of JREs spun up to run applets based on resource usage and security constraints, but there is no guarantee that you can share a JRE. If you have a use case that you want to solve by sharing a JRE between apps you should probably look for a different solution because this approach isn’t going to be supportable or predictable.

Re: 2 JavaFX applets in the same JVM
Gentlemen, Thank you for the informative replies. My understanding with plugin2 and Swing back in Java 6 was that as long as the jvm parameters for each applet were the same, 2 applets on the same html page could share the jvm. I can see, however, that JavaFX running in the native GUI thread would make it really hard to support 2 applets (and therefore 2 javafx.application.Applications) in the same JVM. To Kevin's question, we were looking for 2 things from multiple applets in a shared JVM: 1) reduced resource consumption compared to separate JVMs 2) hopefully easier inter applet communication With a trivial Java 8 update 20 applet needing 141 Meg, if there are several, they can start to add up memory wise. As to #2, we can probably have the multiple applets communicate through javascript (since the javascript support seems to be pretty strong). Not as elegant, but it will probably work.

When you say, below, that only 1 GUI thread is supported (and that thread is the native GUI thread), how are (will?) modal dialogs handled? Thanks, Neil P.S. I've been trying to read Jonathan's article on dialogs on fxexperience.com, but haven't been able to because I get redirected to hosting.xmission.com From: Stephen F Northover steve.x.northo...@oracle.com To: Kevin Rushforth kevin.rushfo...@oracle.com, ngalarn...@abinitio.com, Cc: openjfx-dev@openjdk.java.net Date: 07/08/2014 03:41 PM Subject:Re: 2 JavaFX applets in the same JVM This would imply that there was more than on distinguished GUI thread per process. JavaFX runs in the native GUI thread by design and more than one GUI thread is not supported in JavaFX and on some platforms (ie. Mac).

RT-29969 (and the non-public RT-32321) is about running multiple applets from the same web page, each in their own JVM. By design, JavaFX runs each applet in its own VM. It is very unlikely that we would ever add the ability to run more than JavaFX applet in the same VM. -- Kevin ngalarn...@abinitio.com wrote: Hello, What is the status of running 2 JavaFX applets in the same JVM (separate_jvm = false)? When we try to load 2 applets into the same JVM we get a runtime error (I think it was class loader related). When I searched in jira I found RT-29969 (the 2 applet test it refers to may or may not be in the same JVM) which points to RT-32321 which seems to be private (it gives me an error when I try to access it). Is running 2 JavaFX applets in the same JVM supported? If not, is that a bug or a feature?
