The following tests fail with Java8:

• org.jboss.jsr299.tck.tests.event.observer.conditional.ConditionalObserverTest
• org.jboss.jsr299.tck.tests.implementation.disposal.method.definition.DisposalMethodDefinitionTest

The underlying problem is that java8 returns getMethods() in a different order now. And those 2 tests really depend on the order they are executed in.
The first test method e.g. notifies a Bean which has an IF_EXIST observer method and later asserts that the observer method did not get triggered.
But this test method fails if the other test-methods of the class got executed before it (because of the different method ordering in Java8).
