Java packaging tools - alternatives for jsmooth, launch4j, onejar

I have used these three open source tools for packaging my java apps, but they all look like abandon-ware now. All three are very good pieces of software. What are the options now? (or is using Java for desktop app development no longer a "hot" market for app developers to build & maintain these tools?). 1) exe wrapper: jsmooth - no new development in 2.5 years - does not support 64 bit. launch4j - no new development in over a year, supports 64 bit, but you can't sign the exe created by launch4j, so I prefer jsmooth, but it does not support 64 bit. 2) onejar: It works, but there has been no new development or web site update in more than 2.5 years. So, just want to switch to something that's supported / have a backup plan if it suddenly breaks with a new build of Java. Thanks Edgar
