Incompatible with JDK 8

[slorek]

The current JDK is version 8, but this does not appear to work with torquebox-lite.

When starting torquebox-lite it will get stuck when starting the JBoss AS:

11:05:15,613 INFO [org.jboss.as](MSC service thread 1-6) JBAS015899: JBoss AS 7.2.x.slim.incremental.9 "Janus" starting

Nothing happens after this.

Reverting to JDK version 7 cures the problem.

This issue is more for informational purposes - I'm not sure whether this is a known issue or if support is planned, but if not I suggest an update to the README to point people in the right direction. More than happy to submit this change if it will not be fixed.

The underlying issue is a problem with JDK 8 compatibility in the older version of JBoss Application Server that torquebox-lite bundles.

I'd recommend anyone looking at torquebox-lite instead use TorqueBox 4 alpha builds. The web components are considered stable, and you can pull in just the web with the 'torquebox-web' vs 'torquebox' gem. I'll add a note to the README.
