However, apparently all that kludging inside HotSpot works obviously quite well under Linux. The problem here is that people think that it is going to work under FreeBSD's linux emulation also. > > The FreeBSD port of HotSpot over here is half running.

I think that most of us would like to help you, but I have understood that this is very difficult and complex area to work with. Please try to continue your work - if you don't make it looks like that FreeBSD HotSpot support won't been seen in hear future (at least I haven't heard anyone else working on that) Ari S.
