quarkus-example

An example Quarkus Project suited for more complex examples. Using CDI, JPA, Logging, Configuration and Metering.

Known Issues

Not Java 11 yet, but the folks at GraalVM are working toward it.

Quarkus doesn't respect the test classpath with resources. This leads to resource loading constraints with application.properties and/or import.sql statements that should not be in production code bases.

Member variables are package level variable in order to facilitate the restricted CDI implementation and lack of reflection.
