Mojarra 2.3.0-m06，@PersistenceContext 字段为空

Question

我有这样的转换器：

@FacesConverter(managed = true, value = "myConverter")
public class MyConverter implements Converter {
    @PersistenceContext(unitName = MyService.PERSISTENCE_NAME)
    private EntityManager entityManager;
    ...
}

问题是 entityManager 为空。 faces-config JSF版本为2.3，使用Mojarra 2.3.0-m06。在Application#createConverter() implementation it jumps into the first if's body, but doesn't create the converter. entityManager is not null when the converter is a bean.

我需要在 WEB-INF 目录中添加一个 beans.xml 文件，内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://xmlns.jcp.org/xml/ns/javaee"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/beans_1_1.xsd"
       bean-discovery-mode="all">
</beans>

Mojarra 2.3.0-m06，@PersistenceContext 字段为空
