 before any subclass initialization is performed.

 <p/>Classes that override this method should always call
 <code>super.initFirst()</code> <strong>before</strong> doing
 any of their own work.

 This method loads and initializes all modules
 described in the given implementation advertisement. Then, all modules
 are placed in a list and the list is processed iteratively. During each
 iteration, the <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A> method of each module
 is invoked once. Iterations continue until no progress is being made or
 the list is empty.

 <p/>The status returned by the <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A> method
 of each module is considered as follows:

 <ul>
 <li><A HREF="../../../../net/jxta/platform/Module.html#START_OK"><CODE>Module.START_OK</CODE></A>: The module is removed from the list of
 modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will not be invoked again.
 </li>

 <li><A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_PROGRESS"><CODE>Module.START_AGAIN_PROGRESS</CODE></A>: The module remains in the
 list of modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will be invoked during the next iteration, if there is one. </li>

 <li><A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_STALLED"><CODE>Module.START_AGAIN_STALLED</CODE></A>: The module remains in the list
 of modules to be started and its <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will be invoked during the next iteration if there is one. </li>

 <li>Any other value: The module failed to initialize. Its
 <A HREF="../../../../net/jxta/platform/Module.html#startApp(java.lang.String[])"><CODE>Module.startApp(String[])</CODE></A>
 method will not be invoked again.</li>
 </ul>

 <p/>Iterations through the list stop when:
 <ul>
 <li>The list is empty: the group initialization proceeds.</li>

 <li>A complete iteration was performed and all modules returned
 <A HREF="../../../../net/jxta/platform/Module.html#START_AGAIN_STALLED"><CODE>Module.START_AGAIN_STALLED</CODE></A>: a <A HREF="../../../../net/jxta/exception/PeerGroupException.html" title="class in net.jxta.exception"><CODE>PeerGroupException</CODE></A>
 is thrown.</li>

 <li>A number of complete iteration completed without any module
 returning <A HREF="../../../../net/jxta/platform/Module.html#START_OK"><CODE>Module.START_OK</CODE></A>: a <A HREF="../../../../net/jxta/exception/PeerGroupException.html" title="class in net.jxta.exception"><CODE>PeerGroupException</CODE></A>
 is thrown. The number of complete iterations before that happens is
 computed as 1 + the square of the number of modules currently in the
 list.</li>
