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

[Carlo de Wolf]

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?
