On the Softsqueeze troublshooting page Mr. Titmus provides several hacks to get Softsqueeze to sync with the Squeezebox. The last of those is a command prompt which he requests feedback if that does not work. I cannot find any other way to provide that feedback to him other than this forum. Hopefully he will find this. The command prompt did not recognize the VM option 'UseConcMarkSweepGC'
