A CDI interceptor does not seem to be enabled every time a CDI application is deployed.

To reproduce:
1.) Clone https://github.com/seam/compatibility/tree/arquillian-1.0.0.CR1
2.) Set JBOSS_HOME to point to JBoss AS 7 CR1 installation
3.) run mvn clean test -Darquillian=jbossas-managed-7 -Dtest=EnableInterceptorStressTest

The EnableInterceptorStressTest executes a simple interceptor testcase (EnableInterceptorTest) 20 times. Out of these 20 deployments, the test fails 6 - 13 times (the number varies randomly).
