simulate two instances of Java SE on a single PC
<p>I want to test my middleware (written in Java) on a single PC. That middleware  runs on one virtual device (that has JAVA SE) and the same middleware runs on second virtual device (that has Java SE).  I have a single PC with single operating system. </p>

<p>Would it be possible to simulate two instances of Java SE on a single PC with single operating system ?</p>
