I don't use either java or any browser plugins (other than portable Firefox plugins) so I haven't come across that yet. I used freebsd for a desktop for 6 years, replacing Solaris and not once did I use Linux compat as well. It got shot in favour of windows because TBH that pays the bills better at the moment. FreeBSD however runs a lot of the hidden glue at our company.
