             Summary: Camel-Cdi throws NPE when attempting to inject an array property using Microprofile Config
                 Key: CAMEL-15493
                 URL: https://issues.apache.org/jira/browse/CAMEL-15493
             Project: Camel
          Issue Type: Bug
          Components: camel-cdi
    Affects Versions: 3.4.3
         Environment: JDK 1.8, Tomee 8.0.4 microprofile
            Reporter: Kent Fung


Microprofile Configuration supports CDI injection of properties as lists or arrays and can cause the Camel Cdi extension to throw a NPE during container startup:

This occurs when CdiCamelExtension.shouldDeployDefaultCamelContext encounters a bean for an array type because the Class.getPackage method returns null for arrays:
{code:java}
private boolean shouldDeployDefaultCamelContext(Set<Bean<?>> beans) {

 return beans.stream()
 // Is there a Camel bean with the @Default qualifier?
 // Excluding internal components...
 .filter(bean -> !bean.getBeanClass().getPackage().equals(getClass().getPackage()))
{code}
 

Switching around the equals check should fix it.
