How to get system password from System.getProperties()
<p>System.getProperties() return me all the System properties.</p>

<p>I can see my system user name in <code>user.name</code> property.</p>

<p>Is there a way to get something like <code>user.password</code>?</p>

<p>Note: <em>I have no intention to hack a system</em> :)</p>
