Is the comment on the issue http://fusesource.com/issues/browse/ESB-447 still valid? In particular, is the older version of JSW that is in Fuse ESB able to generate a wrapper for a 64-bit Windows (win7 and winXP) system and start Fuse ESB in a 64-bit JVM?
I'd just comment on the issue, but I guess I don't have the permissions to do that.
