JavaFX the easiest way to get a HTML5 browser in a SWT app? [message #1089751]

It seems JavaFX is the easiest way to get a decent HTML5 browser in my SWT application, are there other embedded HTML5 browsers that support integration with SWT or am I overcomplicating things with the SWT-browser implementations?

My application needs to support 32- and 64-bit builds based on Eclipse 3.8 (or perhaps 4.2) and I have come up with the following solutions where the JavaFX alternative seems to be the only solution that supports both 32-bit and 64-bit and does not force users to perform separate installations.

1. Bundle jfxrt.jar in my plugin (or get it from a bundled JVM) and just display a WebView in a FXCanvas. No other installations necessary.

2. Use SWT Browser with WebKit and force the user to install Safari, doesn't work with 64-bit SWT.

3. Bundle Mozilla XulRunner, also breaks 64-bit support unless running with Eclipse 4.3 and forcing the user to install the Visual C++ 64-bit re-distributables.

Maybe a SWT.JAVA_FX could provide SWT integration with the JavaFx WebView?

WebView is a native component and you need to ship the appropriate DLLs
unless you rely on the one installed coming with the JRE.

Sidenotes:

1.
I guess you know that WebView on 64bit does not jit JavaScript code so
performance for JS heavy apps might be not as good as you'd expect.

2.
If you ship your own jfxrt.jar please note that your stuff breaks if the
Java on the system already has jfxrt.jar because the native DLLs always
take precendence before your custom ones

Thanks, I did not know about the JIT issue on 64-bit architectures.

Issue 2 would only occur if I try to bundle a different version of JavaFX than is already installed on the system, right? Anyway, I think we can get away with bundling the JVM for the application as well so it should be OK.

...ideally I would of course have hoped to be told about some clean way to integrate a decent HTML5 browser in a SWT app without requiring the user to install anything but our own application.
