I don't know how to put the JUnitMemCheckTestRunner under the org.jboss.... package, becouse there are several other JUnit source files that must be modified in order to use the new test runner instead of the old one. Should I rewrite them and put them in the new package as well? If so, wasn't it be easier to copy the original JUnit ant task sources to the org.jboss.... and rewrite them directly instead of extending JUnitTestRunner? It is not possible to move only the modified sources to org.jboss.... package because of package visibility dependencies.
