1) Use the following api:

DateUtil.equals(null, new Date(), false);

Checkpoint: returns with false

2) Use

DateUtil.equals(null, new Date(), true);

Result:

 [render_portlet_jsp:132] null
java.lang.NullPointerException...

Hint: execute it as Groovy-script from Server Admin:

out.println(com.liferay.portal.kernel.util.DateUtil.equals(null, new Date(), true));
