Comment 4 for bug 84501

Example URL: http://argouml-downloads.tigris.org/jws/argouml-0.22.jnlp

To reproduce the bug: open the above URL in Epiphany.

This is a so called Java Web Start file, which uses the web start feature in Java to download the actual .jar file and then run it using the system Java. It doesn't directly have anything to do with the browser, besides the browser downloading the file and handing it to Java. This needs to happen properly, of course. Feisty's Epiphany seems to be not doing its thing properly here, with Java 6. Again, this might be a Java bug, I'm not familiar enough with Java to say, but the fact that it works in Firefox is probably a lead. (Does Firefox use the system MIME configuratoin?)
