Using the 64bit XulRunner in Eclipse SWT under Windows

Is it possible to use the 64bit XulRunner for Windows (available from here) with the Eclipse browser widget? It works fine under 32bit Windows and the answer to this question explains how this works. But when I try this under 64bit Windows I get the following exception:

 org.eclipse.swt.SWTError: No more handles (java.lang.UnsatisfiedLinkError: Could not

   no swt-xulrunner-win32-3834 in java.library.path

Thanks for help, Michael

Edit: I found it in the Eclipse bug-tracker (link here):

swt's 64-bit Windows port does not have xulrunner support because mozilla.org does not provide a 64-bit xulrunner on Windows

But as the last comment on this bug says, there is a 64bit XulRunner available

Yes, XULRunner support on Windows x86_64 is now in place for the upcoming Eclipse/SWT 4.3 release.

Regarding the XPCOM error 0x80004005, if you're trying to use XULRunner 3.6.x (like the poster in the other question) then support for this was released even more recently, see https://bugs.eclipse.org/bugs/show_bug.cgi?id=406912 .
