018 * An {@link org.apache.hivemind.test.ArgumentMatcher} that only compares the <em>types</em> of
019 * the two objects, not their actual values. This is useful for Throwable arguments, (since
020 * Throwables rarely implement a useful <code>equals</code>). This allows a check that the right
021 * type of exception was passed in (even if it doesn't check that the exception's message and other
022 * properties are correct).
