make java startup faster
<p>Is there some way to get reasonable (not noticeable) starting times for Java, thus making it suitable for writing command line scripts (not long-lived apps)?</p>

<hr>

<p>For a demonstation of the issue, take a simple Hello World program in Java and JavaScript (run w/ node.js) on my Macbook Pro:</p>

<pre><code>$ time java T
Hello world!

real    0m0.352s
user    0m0.301s
sys 0m0.053s

$ time node T.js
Hello world!

real    0m0.098s
user    0m0.079s
sys 0m0.013s
</code></pre>

<p>There is a noticeable lag with the Java version, not so with Node. This makes command line tools seem unresponsive. (This is especially true if they rely on more than one class, unlike the simple <code>T.java</code> above.</p>
