Can you create a secure environment when it is, using your own words, "impossible to create bug/vulnerability free code"? I know there have been vulns in the JRE making it possible to break out of the sandbox and similar vulns in the other environments would not suprise me.
It's worth distinguishing between the problems posed by mobile code and the problems posed by ancient programming languages that don't have bounds checking built-in. If I run a pure-java browser, for example, no web site's HTML code is going to cause a buffer overflow in the parser. You'll see a nasty "array index out of bounds" exception, but the stack doesn't get smashed and there is no execution of arbitrary code. That's managed code. OTOH, an applet downloaded from that web site might break the JRE, causing a buffer overflow. If I were running this hypothetical pure-java browser, I'd still be relucant to enable applets because I don't trust the applets and I don't trust the JRE byte-code verifier to validate the applet. That's mobile code.
