It seems like some regression.

When I've tried run like:

mvn3 clean install -Dts.basic '-Dtest=*.jaxrs.*'

I got this result:

[pjanouse@pjanouse testsuite]$ mvn3 clean install -Dts.basic '-Dtest=*.jaxrs.*'
Running org.jboss.as.test.smoke.jaxrs.JaxrsTestCase
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 9.689 sec
...

------ basic module:
Running org.jboss.as.test.integration.osgi.jaxrs.RestEasyIntegrationTestCase
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 13.099 sec
...

So you can see - Integration basic is invoked, but only TestCases org.jboss.as.test.smoke.jaxrs.JaxrsTestCase and org.jboss.as.test.integration.osgi.jaxrs.RestEasyIntegrationTestCas were run although there are plenty of other TestCases fulfilled mask *.jaxrs.* - many of them are localted in testsuite/integration/basic/src/test/java/org/jboss/as/test/integration/jaxrs/ + sub=dirs.
