* This is useful for when you are in a debugging session and you want to go to the source

* along the lines of:
* <pre>
* public class TestFoo extends junit.framework.TestCase
* {
* public void testFoo() throws Exception
* {
* Foo foo = new Foo();
* ...
* assertFoo(foo);
* }
*

* private static void assertFoo(Foo foo)
* {
* try
* {
* assertEquals(...);
* ...
* assertSame(...);
* }
* catch (AssertionFailedException e)
* {
* AssertUtils.throwMangledException(e, 2);
* }
* }
* }
* </pre>
* <p>
* Without the {@code try ... catch} block around lines 11-13 the stack trace following a test failure
* would look a little like:
* <p>
* <pre>
* java.lang.AssertionError: ...
* at TestFoo.assertFoo(TestFoo.java:11)
* at TestFoo.testFoo(TestFoo.java:5)
* at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
* at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
* at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
* at java.lang.reflect.Method.invoke(Method.java:324)
* ...
* </pre>
* <p>
* Note that the source of the error isn't readily apparent as the first line in the stack trace
* is the code within the custom assert. If we were debugging the failure we would be more interested
* in the second line of the stack trace which shows us where in our tests the assert failed.
* <p>
* With the {@code try ... catch} block around lines 11-13 the stack trace would look like the
* following:
* <p>
* <pre>
* java.lang.AssertionError: ...
* at TestFoo.testFoo(TestFoo.java:5)
* at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
* at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)
* at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)
* at java.lang.reflect.Method.invoke(Method.java:324)
* ...
* </pre>
* <p>
* Here the source of the error is more visible as we can instantly see that the testFoo test is
* failing at line 5.
*
* @param e The exception to mangle.
* @param framesToPop The number of frames to remove from the stack trace.
* @throws AssertionError that was given as an argument with its stack trace mangled.
