Running tests-jacc-security on Linux reliably reproduces the error. It can also be reproduced with the following:

$ jboss-4.0.3> run.sh -c jacc
$ testsuite> ./build.sh -Dtest=org.jboss.test.jacc.test.WebConstraintsUnitTestCase one-test
$ testsuite> ./build.sh -Dtest=org.jboss.test.jacc.test.WebIntegrationUnitTestCase one-test

It must be reproduced by running the WebConstraintsUnitTestCase before the WebIntegrationUnitTestCase.
