Re: [jboss-as7-dev] EJB - org.jboss.as.ejb3.pool.strictmax.StrictMaxUnitTestCase accidentally failed (race-condition?)

Usually this would only happen on my hardware. :-) This is a possibility. The test tries to run up 20 threads on a 10 sized pool. In essence your run never got 10 instances going, but only 9. What are your hardware specs?
