On rare occasions in the past, I used Opera for pages that required a 
Java plug-in.

Today I find www/opera no longer working (with 14.0-CURRENT). Whilst 
non-secure <http://neverssl.com/> works, 
<https://javatester.org/version.html> and some other types of secure 
page no longer load. In any case, 
<https://svnweb.freebsd.org/ports?view=revision&revision=563988> it has 
been removed from ports.

Maybe you can run a Java Web Start compatible browser in a jail, or 
Linuxulator?
