This test now simply verifies that the two methods return the same values, ignoring order, so with these changes it's not a particularly good test.

The ordering of methods returned by getDeclaredMethods() is no longer guaranteed as of JDK 7. I think the only way to make this test useful but not flaky would be to skip the test if the JDK is 7 or greater.


assertArrayEquals(fromJvmWithSynthetics, sorted);
