quarkus: NPE when injecting EntityManager/EntityManagerFactory into ObjectMapperCustomizer

Describe the bug I implemented the Jackson ObjectMapperCustomizer and tried to @Inject the Hibernate EntityManager or EntityManagerFactory. On quarkus:dev startup, a NullPointerException gets thrown:

Caused by: java.lang.NullPointerException
	at io.quarkus.agroal.runtime.AbstractDataSourceProducer.getDataSourceBuildTimeConfig(AbstractDataSourceProducer.java:375)

Expected behavior Application should start, EM/EMF should get injected.

Actual behavior NPE, see description

To Reproduce Steps to reproduce the behavior:

1. Check out https://github.com/HonoluluHenk/quarkus-bug-jacksoncustomizer-hibernate.git
2. ./mvnw clean test
3. Watch it crash&burn

Configuration N/A

Screenshots N/A

Environment (please complete the following information):

• Quarkus version or git rev: 1.4.1.Final

Additional context Most specific stacktrace entry:
