Fix for "Several Java virtual machines running in the same process" error

Awhile back, I developed a Java error after I updated Firefox awhile back on my home computer. The error said "Several Java virtual machines running in the same process." I went looking for a solution, and came across this page, which suggests a bunch of stuff, none of which seemed to work (and the page itself didn't even mention Firefox, just IE).

Well, I finally got sick of no Java at home, so earlier this week I kept looking until I found a suggestion in the Sun forums (why they didn't have this on the aforementioned help page, I don't know). It suggests downloading a beta of the Java Runtime Environment. I'm usually cautious with beta downloads, but I don't really get Java that well anyway, and I figured I wouldn't be any worse off, so I followed the link provided to the Java SE Early Access page. I installed "JRE 6 update 10 beta (build 25)," whatever that is, and it fixed the home computer.

I wouldn't have mentioned it except I developed the same problem at work today (don't ask me why it just now started). Downloaded the same beta, and I'm back in business.

Hopefully this will save someone else the hassle.

Again, it's a beta. And I'm no computer expert, so I offer zero warranty. But if you absolutely have to have Java, this may be a fix.

Thank you for this. Same problem, also on Firefox. The JRE6-10 fixed the problem. Hopefully permanently!
