On my mac laptop the test is failing with:
testFileDefaultPermissions(org.jboss.as.test.integration.management.cli.FilePermissionTestCase) Time elapsed: 1.273 sec <<< FAILURE!
java.lang.AssertionError: The test file has unexpected permissions: rw-r-r-
Expected: is "rw-rw-r--"
but: was "rw-r-r-"
at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
at org.jboss.as.test.integration.management.cli.FilePermissionTestCase.testFileDefaultPermissions(FilePermissionTestCase.java:102)

My mask could make the files to be created with these permissions, do we really want to check that?
