There are several problems about the JUnitMemCheckTestRunner. It works now perfetcly, but it was needed to take the whole junit ant task, copy it under org.jboss.... package and change several classes to use the new extended JUnitTestRunner (JUnitMemCheckTestRunner). I would call this solution a bit weird. But I don't have any idea, how to make it better. Do you have any idea or do you consider this solution good? For the JUnitMemCheckTestRunner you also have to change a configuration file inside ant.jar (please see file atteched to JBAS-4211). Now I would like to ask you about adding it to jboss-test project: 1) Where should the new target be? build-test.xml or examples/build.xml? 2) What server configurations should be used? Could it be 'all'? 3) What test cases should be run on the servers for the JUnitMemCheckTestRunner to check the memory?
