org.jboss.cdi.tck.tests.interceptors.invocation.InterceptorInvocationTest.testTimeoutMethodIntercepted() may fail as the timeout notification is delivered after the TCK's timer times out. Although very unlikely, I've seen this happen several times e.g. https://jenkins.mw.lab.eng.bos.redhat.com/hudson/view/Weld/view/Weld%202%20CI/job/Weld-2.x-pull-player-executor/123/console

I suggest to increase the timeout period (1s currently) to e.g. 10s and change the stop condition to

Timing.timeoutAt != null

in https://github.com/cdi-spec/cdi-tck/blob/master/impl/src/main/java/org/jboss/cdi/tck/tests/interceptors/invocation/InterceptorInvocationTest.java#L161
for the test to execute quickly if everything works as expected yet being tolerant to timing issues and slow machines.
