38 <p>This implementation returns the cause that was supplied via one of
39 the constructors requiring a <tt>Throwable</tt>, or that was set after
40 creation with the {@link #initCause(Throwable)} method. While it is
41 typically unnecessary to override this method, a subclass can override
42 it to return a cause set by some other means. This is appropriate for
43 a "legacy chained throwable" that predates the addition of chained
44 exceptions to <tt>Throwable</tt>. Note that it is <i>not</i>
45 necessary to override any of the <tt>PrintStackTrace</tt> methods,
46 all of which invoke the <tt>getCause</tt> method to determine the
47 cause of a throwable.
