Java EE 7 samples: CDI injection fails in some Arquillian in-container tests

Some of the Java EE 7 Samples tests exhibit weird CDI injection issues.

Specifically:

• jpa/jpa-converter
• jta/transactional
• cdi/nobeans-xml

These are all in-container Arquillian tests that construct a JAR archive without beans.xml. The tests fail during CDI injection point validation, because there's no bean suitable for injection.

One other test:

• cdi/bean-discovery-none

Is quite similar: this in-container Arquillian test constructs a JAR with beans.xml which specifies bean-discovery-mode="none". Then, it tries to inject a BeanManager and check that the BeanManager indeed doesn't have any suitable bean for some class. However, the BeanManager itself isn't injected at all, so the test fails with a NPE.

All these tests pass just fine with WildFly.

Steps to reproduce:

# install Swarm with Arquillian fraction autodetection support
git clone -b javaee7-samples-testing https://github.com/Ladicek/wildfly-swarm.git
cd wildfly-swarm
mvn clean install -DskipTests

# set up the Java EE 7 Samples project
cd ..
git clone -b wildfly-swarm https://github.com/Ladicek/javaee7-samples.git
cd javaee7-samples
mvn clean install -DskipTests

# run the test
cd $MODULE # one of jpa/jpa-converter, jta/transactional, cdi/nobeans-xml, cdi/bean-discovery-none
mvn clean test -fae -Pwildfly-managed-arquillian   # with WildFly
mvn clean test -fae -Pwildfly-swarm-arquillian     # with Swarm
