But the Java plugin doesn't. It uses the same platform for browser Java as local Java, which is why it is possible to break out and do things you shouldn't be able to do.

So, no, a browser-specific, limited-API version of Ruby or Python is nothing like running on a full Java VM but trying to constrain what web code can do via the Applet security model. Its exactly like (from a security perspective) in browser JS.
