title: Feed JAVA_OPTS with multiple parameters
body: <p>How do I feed a program with multiple parameters as JAVA_OPTS?
  When I use something like this:</p>
  <pre><code>JAVA_OPTS=&quot;Dx=x1,-Dy=y1&quot;
  </code></pre>
  <p>The value that results for x is &quot;x1,-Dy=y1&quot; and the string is not recognised as list.</p>
  <p>I didn't find any example with multiple values in a list, so I am wondering about the correct syntax, if it is possible at all!</p>
