Log:
Moved nested exceptions for 1.3 compatability to surefire, as they'll be likely 
used there also

+/**
+ * <p>Copied from Spring framework to keep Java 1.3 compatability.</p>
+ * 
+ * <p>Handy class for wrapping runtime Exceptions with a root cause.</p>
+ *
+ * <p>This time-honoured technique is no longer necessary in Java 1.4, which
+ * finally provides built-in support for exception nesting. Thus exceptions in
+ * applications written to use Java 1.4 need not extend this class. To ease
+ * migration, this class mirrors Java 1.4's nested exceptions as closely as 
possible.
+ *
+ * <p>Abstract to force the programmer to extend the class. 
<code>getMessage</code>
+ * will include nested exception information; <code>printStackTrace</code> etc 
will
+ * delegate to the wrapped exception, if any.
+ *
+ * <p>The similarity between this class and the NestedCheckedException class is
+ * unavoidable, as Java forces these two classes to have different superclasses
+ * (ah, the inflexibility of concrete inheritance!).
+ *
+ * <p>As discussed in
+ * <a href="http://www.amazon.com/exec/obidos/tg/detail/-/0764543857/";>Expert 
One-On-One J2EE Design and Development</a>,
+ * runtime exceptions are often a better alternative to checked exceptions.
+ * However, all exceptions should preserve their stack trace, if caused by a
+ * lower-level exception.
+ *

+ * @author Juergen Hoeller

+ * @see #printStackTrace
