  /**
   * Sets up the <em>startup</em> {@linkplain Mock mocks} defined in one or more mock classes, just
   * like {@link #setUpMocks(Object...)} does for regular mock classes. The difference is in the
   * lifetime of the mocks, which will last to the end of the test run. Consequently, this method
   * should only be called once, before the first test begins execution. One way to achieve this is
   * to put the call in the static initializer of a common base class extended by all test classes
   * in the suite. Another way is by configuring what happens at startup through external means.
   *
   * <p>There are three ways to set up mock classes at startup time:
   *
   * <ol>
   *   <li>Define a value for the "<code>jmockit-mocks</code>" system property, as a comma-separated
   *       list of fully qualified class names.
   *   <li>Add a custom "<code>jmockit.properties</code>" file to the classpath, with an entry for
   *       the "<code>jmockit-mocks</code>" (or just "<code>mocks</code>") property.
   *   <li>Specify the "<code>-javaagent:jmockit.jar=&lt;agentArgs></code>" JVM argument, with "
   *       <code>agentArgs</code>" containing one or more mock class names, separated by semicolons
   *       if more than one.
   * </ol>
   *
   * Note that option two above makes it possible to package a whole set of reusable mock classes in
   * a jar file, provided it contains a suitable <code>jmockit.properties</code> file. By simply
   * adding the jar to the classpath <em>before</em> <code>jmockit.jar</code>, the specified mock
   * classes will be loaded and applied automatically on every test run, as soon as JMockit itself
   * gets initialized.
   *
   * @param mockClassesOrInstances one or more mock classes (either <code>Class</code> literals or
   *     fully qualified class names) or instances of mock classes
   * @throws IllegalArgumentException if a given mock class fails to specify the corresponding real
   *     class using the {@code @MockClass(realClass = ...)} annotation; or if a mock class defines
   *     a mock method for which no corresponding real method or constructor exists in the real
   *     class; or if the real method matching a mock method is {@code abstract}
   * @see <a
   *     href="http://code.google.com/p/jmockit/source/browse/trunk/main/test/mockit/MockAnnotationsTest.java#465">

 /**
  * Creates a {@link Proxy} implementation for a given set of interface types. In this created
  * class all methods will be empty, with return values for non-void methods being the appropriate
  * default value ({@literal 0} for {@code int}, {@literal null} for a reference type, and so on).
  *
  * <p>The {@code equals}, {@code hashCode}, and {@code toString} methods inherited from {@code
  * java.lang.Object} are overridden with an appropriate implementation in each case: {@code

  * for the proxy instance; and {@code toString} returns the standard string representation that
  * {@code Object#toString} would have returned.
  *
  * <p>This method is just a convenience for some uses of the <em>Mockups</em> API. In <em>JMockit
  * Expectations</em> in particular, mocked instances will be automatically created and assigned to
