It seems confluence is not happy with my version of java, do I have to install java from source to make it work?

[Nic Brough -Adaptavist-]

I'm not sure it's failing on your version of java, more the config, but I'd try a simple change - use the JRE that's bundled with the Confluence install.

Try setting the java_home to blank and restarting Confluence.  Hopefully it will then pick up the jre that comes with it.  (If not, then try setting it to the jre directory under the Confluence install)
