There're two problems in the arquillian test for demos/policy-transaction at least:

• demos/policy-transaction have a arquillian test case but now it doesn't work due to missing connection factory def as some additional connection factory has been introduced at some point.
• Even if you add connection factory def, the test fails with "No runnable methods" error in spite of having @Test annotation on each test methods. @Test annotation is ignored somehow. jca-* quickstarts doesn't hit this problem, so maybe it's caused by the OSGi related attribute in the MANIFEST.MF.
