/**
* Returns the <code>Class</code> object associated with
the class or
* interface with the given string name. Invoking this
method is
* equivalent to:
*
* <blockquote><pre>
* Class.forName(className, true, currentLoader)
* </pre></blockquote>
*
* where <code>currentLoader</code> denotes the defining
class loader of
* the current class.
*
* <p> For example, the following code fragment returns the
* runtime <code>Class</code> descriptor for the class named
* <code>java.lang.Thread</code>:
*
* <blockquote><pre>
* Class&nbsp;t&nbsp;= Class.forName("java.lang.Thread")
* </pre></blockquote>
* <p>
* A call to <tt>forName("X")</tt> causes the class named
* <tt>X</tt> to be initialized.
*
* @param className the fully qualified name of
the desired class.
* @return the <code>Class</code> object for the
class with the
* specified name.
* @exception LinkageError if the linkage fails
* @exception ExceptionInInitializerError if the
initialization provoked
* by this method fails
* @exception ClassNotFoundException if the class cannot
be located
