title: Closing a ByteArrayOutputStream has no effect?
body: <p>What does this statement, "Closing a <code>ByteArrayOutputStream</code> has no effect" (<a href="http://java.sun.com/javase/6/docs/api/java/io/ByteArrayOutputStream.html#close()" rel="noreferrer">http://java.sun.com/javase/6/docs/api/java/io/ByteArrayOutputStream.html#close()</a>) mean?</p>
  
  <p>I want to make sure the memory in <code>ByteArrayOutputStream</code> gets released. Does <code>ByteArrayOutputStream.close()</code> really release the memory?</p>
  
  <p>Thanks.</p>
