> [NestedWorkAndContextsTestCase#testStartWorkUnsupportedContext|https://github.com/ironjacamar/ironjacamar/blob/1.4/core/src/test/java/org/jboss/jca/core/workmanager/spec/chapter11/api/NestedWorkAndContextsTestCase.java#L171] fails intermittently on slower machines because nested work is started before test itself invokes barrier.await and therefore execution of second work isn't stopped. 
> Expected order of threads is:
> test -- disabled until workA invokes barrier.await())
> workA 
> workB (nested work) -- disabled
> But sometimes it is:
> workA
> workB throws Exception 
> I'm not sure how to fix this correctly but simplest solution seems to be adding Thread.sleep to Work
